1. Conceptual Framework
Derek Clements-Croome
An intelligent building is one that is responsive to the
requirements of occupants, organisations and society.
It is sustainable in terms of energy and water consumptions besides
being lowly polluting in terms of emissions and waste: healthy in
terms of well-being for the people living and working within it;
and functional according to the user needs.
Clements-Croome, 2009
Intelligent buildings need to be sustainable. This means sustaining their performance with respect
to energy, water, waste and pollution for future generations. Beyond this, intelligent buildings
should be healthy places to live and work in; be equipped with appropriate reliable technology;
meet regulations; respond to the needs of the occupants; be flexible, adaptable and durable; give
value for money. Architecture provides landmarks in our civilization so their visual appeal remains
important too.
Buildings will contain a variety of systems designed by people, and yet the relationship between
buildings and people can only work satisfactorily if there is integration between the supply (design
consultants, contractors and manufacturers) and demand (developers, building owners and
occupants) side stakeholders as well as between the occupants, the systems and the building.
Systems thinking is essential in planning, design and management, together with the ability to
create and innovate whilst remaining practical. All this requires holistic thinking. Table 1
summarises the main characteristics of holistic thing in contrast to an atomistic approach.

A lot of terms are used. Should we say intelligent or smart buildings? Then there is the sentient
building which describes how well the building responds to the occupants changing needs. A
sentient building should be measured continually with a sensor network which can predict and also
activate change according to circumstances and user preferences. With respect to cities, the
automation and digital aspects especially in information and communications technology are the
smart elements which are important but a building needs also to respond to social and
environmental factors and this features the language of low tech passive environmental design. An
intelligent building increases the environmental socio-economic value (see Fig. 1).

Figure 1. Key constituents of Intelligent Buildings [Clements-Croome 2013, p. 289].
The ultimate objective should be simplicity rather than complexity and this is best achieved by
naturally responsive architecture. This not only requires technical ability but also the powers of
interpretation, imagination and even intuition. Building Regulations can stifle creations but are
necessary to set a minimum level of expectation and obey health and safety requirements. However
we should aim to design well above these conditions. After all, buildings form our architectural
landscape and they, and the environment they generate, should uplift the soul and the spirit of those
people within them as well as those who pass by them. Clements-Croome [2018] proposes a
Flourish model as a model for user centred design.
The creation of shared visions, effective teams, clear and robust design and management processes
ensures that the intelligent building will effectively demonstrate in use the purpose for which it was
conceived. Times are changing as technology and society evolve so there needs to be a long term
outlook by the team. Key innovation issues for intelligent buildings include sustainability (energy,
water, waste and pollution), the use of 3D and 4D printing technologies, the use of information and
communication technology, robotics, embedded sensor technology, smart-materials technology
including nanotechnology, health in the workplace and social change.
Facades using smart materials for example will provide sophisticated forms of feedback and high
levels of control besides regulating heat air and light transmissions. By coating and embedding
materials with nano-particles we will be able to specify material properties much more easily
[Pacheco-Torgal et al 2013; Pacheco-Torgal and Labrincha 2013]. Structures with zinc oxide nano
coatings for example can accelerate heat dissipation. Self-healing materials will revolutionize
facades in the future. Pelletier and Bose [2010] describe how a concrete matrix embedded with
capsules of sodium silicate healing agent can repair cracks by the sodium silicate from the ruptured
9
capsules interacting with the calcium hydroxide in the concrete to form a gel which seals the cracks.
In contrast one must not forget that basic materials like hemp, straw, rammed earth, waste
composites and wool and seaweed bricks all offer sustainable solution possibilities. Cloth made
from lotus stems was reported in the Financial Times 9 March 5th/6th 2011. Novacem concrete is
a low embodied energy material developed at Imperial College in London. In the future graphene
new material can be expected to make its impact on façade designs.
However innovation should be an enabler rather than an end in itself. Passive environmental design
is equally important so that the energy demands are minimized by using natural means such as
mass, orientation and building form to capture sunlight, fresh air and rain water. But we cannot
ignore the rapid developments in digital technology. In the words of the Hong Kong architect James
Law:
In the 21st Century, buildings will be different from 20th Century. They are no
longer about concrete, steel and glass, but also the new intangible materials of
technology, multimedia, intelligence and interactivity. Only recognizing this
will bring a new form of architecture to light, namely a Cybertecture.

2. Future of Intelligent Buildings: A Critical Debate on Key Performance Indicators
Amirhosein Ghaffarianhoseini, Derek Clements-Croome Ali Ghaffarianhoseini, Husam AlWaer,
John Tookey
2.1 Conceptual framework
In recent years, design and implementation of greener and smarter buildings has indicated growing
trends [Ghaffarianhoseini et al. 2016; Xie et al. 2017]. This is evidently observed in several recent
practices globally, on top of the significantly increased number of research publications in the areas
of sustainable and intelligent buildings.
Notwithstanding the widely well-known concepts of green, sustainable and intelligent buildings,
their embedded essence and ultimate impacts are evolving and adjusting to cultural and social
changes. Current body of literature confirms that, advancement of intelligent buildings (IBs) is
frequently claimed to be a promising solution towards achieving enhanced building performance.
While being efficiently equipped with state of the art technologies, ICT, and automated systems,
IBs are highly responsive to the needs of their occupants besides being optimally operational. IBs
have also proven to be capable of deploying sustainable design initiatives to enhance the overall
performance of buildings and maintain an acceptable level of occupant comfort [Ghaffarianhoseini
et al. 2016; Clements-Croome 2013]. Nevertheless, IBs have been interpreted in many diversified
ways. This complex has led to the true potential of IBs not being fully revealed [Ghaffarianhoseini
et al. 2016; Clements-Croome 2013]. Research endeavours to shed light on the state of the art of
IBs, the most crucial agendas related to their current development, along with their future
directions, as illustrated in Figure 2. As initially suggested by AlWaer and Clements-Croome
[2010] who developed a detailed set of
Figure 2. State-of-the-art Overview of Pathways towards Formation of Future IBs
key performance indicators (KPIs) for IBs and later expanded by Ghaffarianhoseini et al [2016],
and Clements-Croome [2018] to include health and wellbeing and urban scale responses.
11
2.2 State of the Art
Several recent studies endeavoured to define IBs, identify their core attributes and set platforms for
analyzing their effectiveness [Clements-Croome 2018]. Concerning one of the most recent
representation of IBs, six main KPIs are defined [Ghaffarianhoseini 2016]:
KPI-1) Smartness and Technology Awareness,
KPI-2) Economicst and Cost Efficiency to give high value,
KPI-3) Personal and Social Sensitivity and,
KPI-4) Environmental Responsiveness.
KPI-5) Health &Well-Being and,
KPI-6) Urban-Scale Responsiveness.
IBs should go beyond automation and performance dimensions, in order to address a multi-
dimensional set of criteria. This proposal suggests integration with emerging technologies in order
for IBs to become more responsive to users’ needs, value driven and productive [Clements-Croome
2018]. These are on top of becoming adequately adaptable to social and technological changes.
This pathway to achieving smarter environments not only requires deploying cutting edge
technologies (i.e. use of augmented reality (AR), intelligent energy management systems and/or
electroencephalography (EEG) integration) [Vecchiato et al. 2015; Zhou et al. 2016], new design
initiatives (i.e. biomimicry design) [Zari 2016] and advanced digital systems (i.e. real-time data
sensor integrations) but also needs smarter users and professionals. Therefore, it is important to
clarify the interrelated and collective roles of users and communities plus enlightening the
interconnected responsibilities of professionals and academicians, in order to achieve the outlined
targets.
2.3 Future scenario
Are we aware of the current challenges and drawbacks towards development of solid future IBs?
Do we know the exact degree of necessity on the progression of future IBs?
Are construction professionals and building scientists aware of their role in development and
maximizing the ultimate impacts of future IBs?
With the focus of recent studies on the sick building syndrome and the need for healthy buildings
[Xie et al. 2017; Clements-Croome 2018; Heidari et al. 2017], the significance of developing
healthier IBs, to achieve a higher level of comfort, well-being and productivity [Clements-Croome
2017], is emphasized on. Indeed, the healthy design concept is foreseen to become a focal element
for future development of buildings. This is primarily based on its potentials for health
improvement, users satisfaction and the associated economic gains. Besides, as smart cities are
becoming a main focus of governmental sectors [Deakin & Al Waer 2012; Albino et al. 2015],
there is a fundamental need to fill the existing gap between IBs and the smart urban future. As a
result, IBs should also be evaluated from an urban-scale perspective to ensure their contribution at
city-level. In fact, proliferation of IBs plays a key role towards achieving a truly smart city. This is
clearly alongside the urgency for smart infrastructures [Albino et al. 2015]
2.4 Development strategy
Future IBs demand coherent incorporation of cutting-edge digital technologies and building design
in order for their true benefits to be extended. In particular, with the emergence of AR in the
architectural context, from conceptual design and development to the operational phase, integration
12
of AR can be an inherent attribute of future IBs. IBs, as the embodiment of highly automated living
environments, can become more operationally resourceful and user friendly once deploying AR.
Visualizing real-time building and city data in an indoor living environment can be seen as a basis
for new methods of maximizing IBs’ potentials based on the virtual interactions of users, buildings
and urban areas. On the other side, with the emergence of robotics in architectural design and
construction, IBs can not only benefit from a more efficient development process (i.e. use of
robotics in off-site construction, prefabrication phases and parametric design), but can also be
equipped with robot-assisting living environments during the operational phase to enhance safety,
security and comfort. Furthermore, from a neuroscience perspective, future IBs not only need to
be aware of their impacts on comfort, well-being and satisfaction of occupants, but also should be
cognizant of occupants’ mood, sensation and feeling via monitoring the brain responses of their
users using EEG. Meanwhile, the importance of integrating IBs with Building Information
Modelling (BIM) for life-cycle design, operation and maintenance of buildings is signified
[Ghaffarianhosein et al. 2017]. Thus, presenting an interdisciplinary development strategy, IBs of
future will push the current boundaries to autonomously receive and analyze the real-time impacts
of their embedded living environments on the mental responses of theirs users and their health
status, plus their influence in the urban-scale performance of the city. This can result in
development of ultra-healthy IBs for more tangible contribution to the well-being of occupants and
the performance of a city.
2.5 Research Contribution
IBs should be seen as a research-based evolutionary entity that requires continuous upgrade and
incorporation of new initiatives both from professional practice and academic perspectives.
Literature presents that IBs were repeatedly suggested to become the main umbrella encompassing
several targets for achieving green, energy efficient, zero energy, zero carbon, smart and digital
built environments. This allows synchronizing all attributes in one set of database for a collective
contribution to the next stages of IB development. Above this contemplation, to the best knowledge
of the authors, no or very insignificant number of studies have attempted to discuss the gap between
IBs and smart cities. In fact, for achieving intelligent urban areas as part of a smart city [Albino et
al. 2015], despite the existence of several drawbacks towards a massive proliferation of IBs in an
urban area, with the aim of large-scale contribution to the goals of smart city, more in-depth
analysis on IBs is required to be carried out.
2.6 Research Agenda
There is no doubt that a key agenda of the 21th century is to amplify the awareness and propose
practical solutions regarding the impacts of rapid urbanization [Lehmann 2017]. While to some
extent, the rapid urban growth in many mega cities and their surrounding context is inevitable, this
study suggests that utilization of IBs, once fully assessed from both building and urban scale
perspectives, can provide significant positive impacts. In particular, the study demonstrates that
IBs embrace a huge capacity for reducing the negative environmental impacts of urbanization,
balancing the digital lifestyle of users with living and working environments plus providing
healthier indoor living environments and urban communities. The conceptual framework also
implies that IBs can be the central point for formation of smart communities and their large-scale
performance besides their real-time data integration at city level can uplift the performance of a
city. Likewise, it is elaborated that integration of BIM, AR technology, robotic-based environments
and neuroscience-based building design are four core lines of future IB developments. These new
dimensions of IBs create a wide platform for more in-depth interdisciplinary research to create the
IBs of future from architecture, building construction, digital technology and ICT to urban design,
13
city planning and computational parametric modelling.

3. Health and Wellbeing oriented Indoor Built Environments for Future Intelligent
Buildings
Quan Jin, Holger Wallbaum
Highlight
Aiming to improve the quality of life for living, learning, curing and working in future intelligent
buildings in terms of offering advanced indoor built environments, which takes advantage of
reliable and supportive technologies, and is rooted in evidence and resilient design thinking and
human real demands targeting human health and wellbeing along with low environmental impact
and high economic performance over the whole building lifecycle.
Scope
Considering “health and wellbeing” in intelligent buildings, ecologically sustainable design,
indoor environmental qualities, smart metering and control strategies, energy efficient
technologies as well as user demand are interrelated closely. This chapter discusses the key
features for human health and wellbeing in buildings as well as research gaps between the real
perception from user side and the measured building performance. Key research questions are put
forward that need to be answered. Research and development concerning knowledge, tools and
technologies are initiated. Finally, new horizons for the future built indoor environment of
intelligent buildings are depicted.
3.1 Status quo
Looking back on the progress of intelligent buildings since the year 2000, the content of quality of
life and users’ interactions have been being taken into play as one of the evolutionary strategies.
Quality of life makes contributions to the key performance indicators of social well-being and
economic efficiency and the specific visions of human health and well-being are one of the key
criterions in intelligent buildings’ classification. Particularly in next generation office buildings,
user-oriented lower carbon footprint, and resilient office design solutions are to be implemented
for future. A circular design process instead of conventional linear design is created to holistically
integrate multidiscipline and diagnose the real demand from users and stakeholders during the
whole building lifecycle [Cobaleda Cordero et al., 2018].
Human health and wellbeing are more commonly known as a positive factor to human
productivity in particular for offices [Wargocki et al., 2000; Fisk, 2000]. Productivity is one of the
key drivers taking the utmost benefits to building stakeholders. High work productivity of the
employees and less sick leave absences could be seen as a game-changer in future intelligent
buildings and sustainable office buildings [Feige et al., 2013]. If we contribute to reducing the
staff costs in the operational phase through energy efficiency measures and a better indoor
environmental quality (IEQ), then we can argue for higher investments on energy efficient and
innovative technologies as well as human wellbeing. It has been concluded that if only 10%
variation is made by our effort from staff costs, 9% cost saving can be realized in total during the
operation phase of buildings (see Fig. 3.2).
15
Figure 3.1. Linear design process vs circular SSO design process [Cobaleda Cordero et al.,
2018]
Figure 3.2. Typical business operating costs regarding energy, renting and staff. Source:
Health, Well-being & Productivity in Offices, World Green Building Council,
Sept. 2014 [WGBC, 2014]
There are more and more indications that a good IEQ in office buildings positively contributes to
the well-being of occupants, reduces sick leave days and finally, leads to an increased productivity
[MacNaughton et al., 2018]. These so-called co-benefits could be seen as a driver for more energy
efficient and healthier buildings in the future - saving costs for both businesses and the society.
When concerning the other way round, the consequences of occupant discomfort and ill-health
16
caused by bad IEQ finally can lead to low work performance and more sick leaves. IEQ in terms
of thermal climate, air quality, acoustic and lighting and daylights have a noticeable impact on
human comfort, health and productivity which have been selected as mandatory indicator listed in
sustainable building rating systems, e.g. WELL, GREEN STAR, BREEAM, LEED, DGNB,
Miljöbyggnad, GBI. IEQ needs to be designed and optimized to maximize human well-being and
productivity. But sometimes the building design may not create a better indoor comfort and one
of the reasons is that we lack of an interdisciplinary study and the cross-disciplines knowledge
frame from the physical climate, architectural design, organization environment, as well as social
and cultural background of the users.
Beyond IEQ, the other disciplines regarding ergonomic interior design, space function and
flexibility use, new user behaviour patterns and work demand need related aspects have been
considered [Schiavon & Altomonte, 2014; Kim & de Dear, 2013]. In different building typologies,
e.g. offices, apartments, schools, health care centres, elderly home, the specific living and working
environments needed from different groups of users should be customized and used for a
convenient and efficient living in intelligent buildings. Up to now, the interrelation and interaction
of different factors are far from clear, hense a holistic and evidence based design and optimization
in future intelligent buildings is exceedingly demanded.
To generate knowledge on buildings and users and their interactions, fundamental studies [de
Dear et al., 1998; Zhang et al. 2010] have been conducted on exploring the mechanisms of how
humans perceive the indoor environment, what are preferred indoor environment, and what are
the key indicators regarding both physiological and psychosocial aspects, for example, skin
temperature’s reaction to thermal comfort’s change and gender’s differentiation on the preference
[Jin et al., 2016]. Based on new knowledge explored in intelligent buildings embedded smart
sensors, meters and automation systems with the human physiological condition, behavioral data
and building performance monitoring and information communication technologies have been
being extensively applied. An outcome is to match human real demands, preferences and
changing behavioural patterns with responsive and adjustable indoor environments and low
energy use through intelligent control strategies, for instance, smart grid and demand response
control.
Nevertheless, health and wellbeing are more complex on the mental and perceptual levels than it
can be predicted only based on the results of measurable building performance parameters
[Bluyssen et al, 2011]. There are still many knowledge gaps concerning human real demands and
the designed indoor built environments such as a comprehensive understandings of how various
factors affecting health and wellbeing, what are the biases existing between human real demand
and building performance, etc. However, existing datasets are still limited to identify all related
factors and quantify the influencing relations to truly achieve sustainable indoor built
environment in different typologies of intelligent buildings. Obviously, there is a demand to
gather sophisticated information on occupants’ perception and behaviour as well as various
building performance related aspects such as energy efficiency levels, the role of smart materials,
and potentials of smart technologies. This demand is seen globally but a localisation is required to
adequately address socio-economic and cultural differences.
17
3.2 Research and Development
Global database development: Data collections on energy performance, IEQ and occupant health
and wellbeing from existing and new buildings need to be conducted further towards a cutting-
edge database set up concerning climate, social and economic conditions. The database
development will be a crucial bridge to conquer the gaps between human demand and building
performance. More concerns will lie on the data from occupant perceptual and real-time indoor
comfort and health, user behaviour and preference, measured energy performances, and from
building features on building typologies, user information, indoor environmental qualities, interior
components and landscape and low-carbon technologies.
Information communication technology (ICT) embedded data collection and internet of
things (IoT): A long-term and longitudinal data collection process is to be promoted to help to
visualize the mega field data as “right here, right now” with detailed insights to a dynamic indoor
climate and human demands. Embedded ICT equipment and system will allow an intelligent and
distance monitoring of various building technologies and equipment. IoT will implement much
smarter ways to connect personal equipment and device according to individual preferences of
comfort and cost and energy consumed concerns allowing communications between smart meters
and smart grid, such as the adjustable orderings of personal heaters, windows, self-ordering
fridges, washing machine at low energy tariff times, and surplus energy back to the grid.
Insights tools and analysis platform: Advanced and instant qualitative and quantitative insights
tools to collect occupant responses on comfort, health and wellbeing are to be developed
integrating different expertise of engineering, architecture, psychology, physiology, etc. A web-
based platform to visualize instant data collected will efficiently transfer building performance
and occupant real demand to building stakeholders and provide recommendations for building
service systems and human behaviours.
Sustainable technologies for advanced indoor environments: Intelligent buildings should be
better featured by human-oriented built environment design and environment-friendly indoor
climate technologies. When considering to improve human health and wellbeing, more sustainable
technologies regarding energy efficient building design, low impact construction and ergonomic
services should be identified and applied to provide advanced indoor climates achieving a higher
sustainability performance.
3.3 Future Horizons
– Health, wellbeing and low energy use based indoor environment design will be tailored for
different groups of end users regarding building typology, personal comfort profile and
office “DNA”. A holistic understanding of the factors existing in buildings and from the
user perspective will be generated in depth to promote a knowledge evolution on the
conceptual creation and strategic plan in future intelligent building development and
construction.
– Human real demand to be fulfilled by reliably smart technologies and resilient indoor
climates with “surplus energy” balance. Long-term monitoring of indoor environment as
well as human behavior and occupant feedback gathering systems will be commonly
embedded in the future buildings to fully access the real-time information and conduct
artificial intelligence analysis with the big data collection.
18
– Maximize the benefits through social, environmental and economic dimensions when
creating a living environment for humans. The added values of improved comfort, health
and productivity will be further quantified and emphasized compared to the mere energy
perspective in future buildings aiming for a better sustainability. New indicators and indices
will be developed to sophisticatedly evaluate the performance of the next generation of
intelligent buildings.
Chapter 3 aims to emphasise human health and wellbeing in indoor environments for future
intelligent buildings along with low environmental impact and high economic performance
over the whole building lifecycle. Quality of life makes contributions to the key performance
indicators of social well-being and economic efficiency, and the specific visions of human
health and well-being are one of the critical criterions in intelligent buildings’ classification.
Particularly in next-generation office buildings, user-oriented lower carbon footprint, and
resilient office design solutions are to be implemented for future.
This chapter discusses the key features of human health and wellbeing in buildings as well as
research gaps between the real perception from the user side and the measured building
performance. Fundamental research questions are put forward that need to be answered.
Research and development concerning knowledge, tools and technologies are initiated.
Ultimately, new horizons for the future built an indoor environment of intelligent buildings are
depicted.
The highlight of the conclusion is offering advanced indoor built environments for the future
building users, which takes advantage of reliable and supportive technologies, and is rooted in
evidence and resilient design thinking and human real demands. A circular design process
instead of conventional linear design should be utilised to holistically integrate multidiscipline
and diagnose the demand from users and stakeholders during the whole building lifecycle.
Future R&D activities are needed as global database development, ICT embedded data
collection, as well as sustainable technology implementation for advanced indoor
environments. In a nutshell, we anchor three horizons: health, wellbeing and low energy use
based indoor environment design, fulfil human real demand, as well as maximize benefits of
living indoor through social, environmental and economic dimensions

4. Technology Aware Workplaces
Matthew Marson
4.1 Introduction
Often, with intelligent buildings, it is found that lots of technology is implemented for
the sake of technology – a demonstration of technical prowess. The vast majority of
the systems implemented are for energy management. For knowledge-based
industries, energy accounts for only 1% of the operation costs, yet real estate costs
account for 9% and employees’ salaries and benefits account for 90% (JLL, 2017).
Therefore, human-centric design is, in fact, a more appropriate way to design use
cases, select technologies and operate a building, helping businesses to achieve their
wider outcomes.
Globally, workplace design is being increasingly important and relevant to business
outcomes (Morgan, 2017). By being culture-centric, a business can demonstrate a key
differentiator in a market of homogenised remuneration packages.
Noteworthy workplaces often feature fully integrated suites of technology. Having
workplaces that are adapted in real-time, using technology, allows a business to reduce
the productivity leakage of their workforce. Productivity leakage is the sum of all the
pain-points that an employee experiences during the day that prevent them from doing
something productive. This could include a faulty coffee machine, waiting for an
elevator or voice-over IP technology that repeatedly fails. Sodexo believe that most
white-collar workers experience around two hours of productivity leakage a day. For
most businesses, this means that 25% of the working day is lost due to workplace
inefficiencies. This represents a significant cost to the business. This paper will outline
some examples across the below three value levers:
1. The Change Role of Technology in the Workplace
2. Wellness & Productivity
3. Social Collaboration & Space Optimisation
4.2 The changing roles of technology in the workplace
As robotic automation replaces the jobs of those doing repetitive tasks, the workforce
of the future will be performing tasks that leverage non-automatable skills such as
creativity, communication, innovation or collaboration. Often, workplaces are designed
for a single person to sit at a single desk. This kind of design restricts fluid ways of
working. The fundamental technology delivered in the workplace will become more
consumer grade and more flexible and mobile than ever. Those working across
geographies or from co-working or café spaces need enterprise technology that is as
malleable as the expectations of a person performing a role.
The workplace is becoming more of a destination. IBM, the company that championed
telecommuting for the vast majority of its history, is now recalling its staff to the office.
The company believes that their employees need face-to-face interactions in order to
develop their products and services, as well as be more engaged.
New methods of business such as a design thinking and agile development need
different types of spaces and technologies. Design thinking requires collaboration
21
rooms for sticky note activities. Agile development needs ceremony space with audio-
visual equipment that can demonstrate a software product. This means that the
technology provided in the workplace needs to be integrated into the fabric of the
building, in the fabric of the organisation and be well integrated to reduce support
over-heads and productivity leakage.
4.3 Wellness & Productivity
The optimisation of the physical environment goes hand-in-hand with the productivity
of the employees and their health and wellbeing (Stoddard, 2016). Delivering a
technology empowered wellness programme to the workplace can help a business
reduce its employee’s sick days by 28% (ERS Research & Consultancy, 2016).
For example, by having a set of sensors linked to an Internet of Things (IoT) platform,
it is possible to automate the control of internal air quality. In a meeting rooming, it is
possible to observe the levels of CO2 increase over time. When CO2 levels in a space
are too high, the ability to make decisions and to concentrate plummets (RESET air,
2016). By comparing the rate of CO2 production with the occupancy (gathered from a
mesh of quad-pyro passive infrared sensors) from a connected lighting system and the
design values of the space, machine learning can be applied to control the volume of
fresh air being delivered to that space. This way, the building can autonomously keep
the internal air quality as healthy and productive as possible.
The industry is also seeing the growth in demand for circadian lighting. Circadian
lighting has two main types. The first type ‘daylight harvests’. This means that it only
adds synthetic light in addition to what natural light is not providing. The driver for
colour temperature is still the sun. The second type of circadian lighting synthetically
controls the colour temperature to mimic the sun. Both have been shown to be far less
disruptive on a person’s circadian rhythms. Technology can also be implemented on
occupant’s laptops and phones that make the back light of the device follow the
circadian rhythm. This means that the employee is able to get to sleep naturally and is
therefore more productive the following day. This use case combined both energy
efficiency and health for the business imperative.
Productivity leakage can also occur through the lack of availability in concierge-type
services. The ability to ask simple questions with an emotional touch helps employees to
be more effective when dealing with organisational policy. Today, we are seeing
customer services organisations implement artificial intelligence chatbots to deal with
high customer demand. This significantly reduces the operational overhead whilst
delivering a sentiment-based response. Fjord believes that artificial intelligence will be
the user interface of choice in the future. By implementing this kind of technology in a
building, employees will be able to adjust room settings, find available spaces on the
fly, check the status of requests and much more. We will the growth in the concept of
building service user interface in line with consumer liquid expectations.
Beyond voice, video will also be used to measure the sentiment of employees. Linking a
series of cameras to a video analytics platform will analyse the facial expression and
postures of employees to understand their mood. This means that the building can
intelligently adapt the surroundings to increase comfort. Perhaps when it looks like
someone is having a bad, the building could reward them with an increase. These sorts of
22
ludic or delight events inspire employees and keep them engaged.
4.4 Social Collaborations & Space Optimisation
The management of space can often cause dissatisfaction in the workplace. The ability
for employees to query real-time utilisation data, means that they can make decisions
on where to go for some focused time, or a private call. They can also make an
intelligent decision on when it is good to go to the canteen. Being able to expose this
data in a user-friendly way is often a challenge for real-estate departments.
Knowledge workers rely on the knowledge of others. In large organisations, the ability
to connect and speak to others is often achieved through social knowledge as
corporate directories are often hard to navigate and do not relate to the physical world.
Implementing a set of location services in a building allows a culture of collaboration
to be achieved. Today, if you need to find someone with analytics skills for the project
that you’re working on requires you to email someone that may know someone. Before
you know it, you have been passed through tens of connections. By integrating the
location of employees (through WiFi triangulation or a Bluetooth beacon enabled
mobile app) to a skills database, means that colleagues can now connect faster with
those in the same building. This reduces productivity leakage and increases
interdisciplinary interaction. For businesses wishing to be more innovative, the
building can force social collisions by displaying interesting information about those
in the immediate vicinity to start a conversation.
This sort of technology often creates privacy concerns. By ensuring that the employee
has to opt-in into different levels of privacy, means they are more forthcoming with the
vision. By limiting the display of data to back-end, the front-end, then biometric
systems, employees are able to expose as much or as little data as they are comfortable
with. The ability to switch on and off on demand is an import control that makes the
populous feel more comfortable.
Location services can also be leveraged to reduce productivity leakage by giving the
ability for employees to rapidly find a thing (such as a high-value or well-used piece of
equipment). This allows an organisation to make better use of scarce resources and
maintain assets properly. It also allows individuals turn-by-turn navigation to parts of
the building that they are unfamiliar with. This helps visitors and temporary employees
get their bearing within a building.
23
4.5 Summary
The clear majority of the use cases above can only be achieved through comprehensive
integration of legacy and additional systems throughout the building.
Traditional building management systems are not sophisticated enough to deal with
the number of integrations, or computations. Having a connection to a cloud-based
IoT platform, means that buildings can have new applications installed to unlock
enhanced automation or other use cases.
As the line between the physical and the digital continues to blur, we will see the
increase in technology in the workplace.

5. Daylight in Intelligent Sustainable Architecture
Juergen Koch
5.1 In general - Daylight and its Importance:
Daylight is the basis of all life and growth. It controls our organism and has a significant
influence on our health, performance and well-being. Daylight serves not only to see, but gives
us spatial orientation, orientation to the time of day and season because orientation is essential
for our well-being as well.
Being without orientation is a terrible condition that can be caused by illness or is generated
by external circumstances for that architects and engineers sometimes are responsible for.
The sun can be used for heating our buildings as well.
Winter gardens or roof glazed atriums are excellent examples as so called climate puffers.
Daylight is, however, also the most natural free resource.
Why we don’t use it more intelligent in architecture is incomprehensible and irresponsible.
5.2 "Daylight cannot be replaced by anything"
How do we use daylight in commercial architecture today?
What is the “status quo”?
Historic Daylight Architecture - Cologne Cathedral Seagram Building New York City
1958
Architects and inhabitants has always the dream of buildings having a clear and wide view
into the environment and nature and at the same time being protected from the elements. With
the development of even better and larger glazing’s, this dream came true after World War II
since the middle of the last century. The famous architect Mies van der Rohe was one of the
protagonists in "Bauhaus" architecture and masters of reduction to the essentials. The Seagram
Building (1958) in New York City is one of the most famous skyscrapers representing this
dream. But Gothic cathedrals show the fascination of daylight and large glazing’s as well
centuries ago.
More daylight in architecture was the reaction to the narrow, dark and unhealthy housing
conditions that with the first industrial revolution led to inhuman conditions in rapidly growing
industrial cities.
25
With large glass surfaces are not only benefits came up. Direct solar irradiation over large
glass surfaces also leads to glare of the occupants and to overheating the interiors. Internal
glare protection and air-conditioning systems have to heal the deficiencies of our buildings
with a huge energy input.
By the mid-seventies of the last century, oil was cheap and no one was looking for more
intelligent solutions. Glass industry and refrigeration industry became very good friends from
that times.
In many commercial buildings the cost of HVAC rose to 40% of the total construction costs.
Despite these problems, large-scale glazed buildings have not lost their fascination to this days.
„The dream is still awake.“ But we have to solve the problems so that the dream does not
become a nightmare.
It was first the oil crisis in 1972 and the publication of the Club of Rome report,
"The Limits of Growth," which led to a trend reversal.
Initially, architectural concepts were developed in housing construction, which attempted to
make climate-friendly residential buildings with passive natural resources. Winter gardens,
which captured the heat of the sun for heating purposes, became modern again. But in
commercial buildings, little has changed as far as the intelligent use of sunlight is concerned.
So far, we have come up with no better idea than shielding the glare and turning on the artificial
light when the sun is shining. With some luck, the caretaker turns off the lights at night. In
many commercial buildings artificial light burns all night until morning. This is absolute
nonsense and is the opposite of intelligent buildings.
So the answer to the question how we use daylight in commercial architecture is:
We use it just a little and that in a stupid way. This is totally crazy and quite primitive compared
to the automotive industry for example or the digitalised world in other areas. The internal sun
protection/blinds can only be used as glare protection. The solar heat still reaches the rooms
and causes cooling. That means, sunlight causes energy need. It should be exactly the other
way around.
It is time to use sun and daylight more intelligent for our buildings and cities7public areas.
Daylight Architecture is one of the most intelligent ways to use free renewable energy and
increase comfort, health and well-being in our buildings and by the same time reducing carbon
emission.

of the Year 2014-Green Building
5.3 What can be done better to use the sun and daylight more intelligent?
Using daylight and the sun more intelligently not only means better light quality, health, comfort
and well-being for the user, but also a reduction in heating and cooling requirements and the
associated waste of energy and at the same time reducing CO2 emissions.
We have to control the daylight in a better way so that less heat enters the interior. Integrated blinds
in between of triple glazing can, for example, be a good solution. However, since daylight is not
constant, but constantly changing, intelligent buildings must react to it automatically. By the same
time the blinds are closed a part of the daylight reaching the window should be used intelligent.
This means that modern facades and conservatories should respond to weather conditions, sun
exposure and intensity and changes in the use of the building.
The components are:
1. Daylight redirection elements.
2. Efficient electrical sun- and glare protection system.
3. Control system which regulates the sun protection system automatically.
4. Sensor-controlled LED lighting, which reacts automatically on the daylight offer.
5. One or two weather stations on the roof of the building.
6. A clever person who writes the program for the control system.
To control the blinds a program has to be written that is adapted to the building, its use and
its natural and social environment.
27
This system is not really complicated, but it is complex. It reduces the power requirement for
lighting up to 25%. At the same time it ensures that less cooling and heating is required. This
means, of course, that the control system must be connected to the overall building control
system as well. The areas that are supplied with natural healthy daylight can be doubled. In
this case, improving comfort, well-being and health of employees means that the productivity
of employees in these buildings is much better.

5.4 Conclusion:
Why we do not more of these? Are there industrial interests blocking new technologies?
To design und realise more intelligent green and sustainable buildings does not mean to put
on something on traditional construction methods and systems to make them more
expensive, it is about to change something in the process of planning and to integrate and
cultivate new technologies in our architectural design language. It is called IED, Integrated
Energy Design. That means for example, the quality and functions of façades are becoming
of more importance and connected holistic systems are required instead of the traditional
addition of separate systems. But it also means, that the money for construction is moving
from the old technical centres into the outer skin of sustainable intelligent buildings.
In commercial buildings of course are other and additional ways of using daylight than in
facades are recommended, like roof lights. But that means for example for supermarkets, to
control the incoming light as well but in a generally similar way as in facades.
It is all about connecting and combining different systems to control the daylight in our
buildings and our buildings must be able to react on changing weather- and use conditions.
The panning instruments have to consider different dynamic processes over the year, so we
use dynamic simulation programs optimising the relationship between buildings and the
changing environment conditions, like in a living organism.
The dimensioning of technical aggregates, based on worst case conditions, is of the past.
It is about optimisation and using synergies to get more intelligent buildings.

But one thing always has to be considered first, people. People should always be in the focus of
everything that architects and engineers do. It's not about what's technically possible. We need to
be careful not to get over-engineered buildings, we need robust and resilient solutions because
human habits in building use are different and are not a constant factor in all engineering
calculations, as the computational models often suggest.
Buildings and their technical systems need to be intelligent, but also easy to handle.
Daylight Architecture is one of the most intelligent ways to use free renewable energy and
increase comfort, health, well-being in our buildings and reduces carbon emissions,
hopefully soon.

The quality, complexity and functions of facades are becoming more important and
connected holistic systems are required to control the daylight, artificial light, heating,
cooling and ventilation. Dynamic simulation programs can help to optimise the relationship
between buildings and the environment.
But one thing has to be considered first, people should always be in focus of everything that
architects and engineers do. It's not about what's technically possible.
Around the country we need better legal regulations regarding minimum distances between
buildings related to their height, so that architects and engineers get the chance to use the sun
more intelligent for well-being.
We also have to be careful not to get over-engineered buildings, we need robust and resilient
solutions because human habits are not a constant factor in engineering calculations, as
computational models often suggest. Buildings need to be intelligent, but also easy to handle.
Controlled daylight use in buildings is one of the most intelligent ways to use free renewable
energy and increase comfort, health, well-being in our buildings and reduces carbon
emissions, hopefully soon.

6. Intelligent Infrastructure
Mark Worall
6.1 Conceptual framework:
Buildings are one of the priority areas for tackling urbanisation issues through smart city initiatives
(Airaksinen, et al, 2016). Intelligent buildings will play major roles in tackling energy, resource
and environmental issues and the intelligent buildings roadmap will set out many of the challenges
facing the sector, but also opportunities for advancement. However, intelligent buildings developed
in isolation will not be able to fully address the challenges and will therefore not in of themselves
provide optimal solutions.
Figure 6.1. Buildings, the city and its infrastructure
Buildings are a part of a complex ecosystem that displays many of the features of living organisms
(Nilon, et al, 2003) – flows of energy and matter, flows of information, interaction with the
environment, rhythm, growth and decline and evolution. Historically, buildings and the
infrastructure connecting it to other buildings and services have had no interaction apart from such
one way processes such as metering and billing.
If buildings are seen not as individual entities, but as dynamic components in that ecosystem, then
“intelligent infrastructure” should be considered as the distribution system connecting individual
intelligent buildings in a multi-faceted, interactive network.
Infrastructure connects buildings to the wider community through networks that have functions as
diverse as the supply of services such as electricity, fuel, water and communications, the removal
and treatment of waste such as sewage and refuse, and the movement of commuters through road
and rail networks.
Buildings have a wide variety of uses, ranging from residential dwellings, office and commercial
buildings, retail, catering and leisure centres, public buildings such as schools and hospitals,
factories, warehouses and distribution centres and data centres and server buildings. The wide
31
range of services networking with buildings and the diverse range of building type and usage
pattern means that intelligent infrastructure can allow individual buildings to operate whilst the
infrastructure enables the system as a whole to be optimised.
Figure 6.2. Diagram indicating the interrelationship between social, environmental and smart
elements that defines intelligent buildings and infrastructure.
Intelligent buildings and infrastructure enables buildings to be productive and cost-effective
environment based on three basic intersecting elements;
social
smart
environmental
Social
We spend over 80% of our time in buildings (Klepeis et al, 2001) and the needs and desires of
people manifests itself in demand for services and consumption of resources. Developing
intelligent buildings and infrastructure that respond the people’s needs will contribute to well-being
whilst addressing the capacity of the environment to meet these needs in more sustainable ways.
Smart
Infrastructure is becoming connected through advances in information and communication
technologies (ICT). Internet connected sensors and devices are becoming more and more available
and it is projected that there will be over 26 billion connected devices by 2020 (Evans, 2011).
Recent advances in areas such as complexity modelling, data mining, deep learning, AI, and the
internet of things (IoT) could enhance the drive to more efficient use of resources and the
optimisation of buildings and the infrastructure serving the needs of people. These developments
present many challenges, but also opportunities for advancement (El-hawary, 2014).
Environmental
Buildings use up to 40% of the world’s energy resources, around a third of carbon dioxide
emissions and 10% of water withdrawals, so the provision of electrical power, heat, water and
waste are important for developing sustainable building services. Until recently there has been a
one way relationship; energy and water was delivered and waste was removed; but the advent of
smart grids and intelligent networks is meaning that the management of resources is becoming
more dynamic and responsive. Two of the main services vital to buildings and the people using
them are energy and water. Energy and water are inextricably linked. Water is necessary for power
32
generation and energy production and energy is needed for water extraction, processing and
delivery and this interconnectedness is sometimes referred to as the water-energy nexus. Intelligent
infrastructure will integrate the production and distribution of energy and the provision of water
and waste services.
6.2 State of the Art
Social infrastructure
Challenges
Health: As urban population density and GDP increases, energy consumption, water demand
and transport use will increase. The health, safety and well-being of people, especially
vulnerable sections of society such as children, the elderly and people with underlying health
conditions will be harmed due to increases in pollution, emissions and inadequate sanitation.
The infrastructure connecting buildings to its services will need to balance the demand for
services with the needs of people for good health.
Wellbeing: The WHO states: ‘Health is a state of complete physical, mental and social well-
being and not merely the absence of disease or infirmity’. The term ‘well-being’ reflects
one’s feelings about oneself in relation to the world. Many issues contribute to health and
wellbeing either positively or negatively, and intelligent infrastructure can contribute to good
outcomes and mitigate poor outcomes.
Employment: Intelligent buildings as workplaces, provide environments in which people
perform tasks in a productive and cost effective manner, but in which their well-being is not
just an afterthought, but is part of the process. However, the development of automation,
robotics and artificial intelligence (AI) could see the loss of jobs over a wide range of
occupations. Frey and Osborne (2017) predict that up to a half of total US employment is at
high risk of being replaced by computerisation and automation.
Job losses: Buildings designed to support sectors vulnerable to computerisation (low skilled,
low wage sectors) would be surplus to requirements and would need to be modified in order
to cater for newer job categories, converted to other uses, left unoccupied or be demolished.
This would present challenges to;
o The owners of buildings, due to the loss of revenues over a building’s lifetime, costs
of conversion to new use, or costs of demolition and rebuild.
o The users of building in emerging job categories, should buildings not be fit for
purpose, which could lead to frustration, reduced job satisfaction and lower
productivity.
o Architects and urban designers, due to the need to refurbish existing buildings or
creating new buildings suitable for emerging job categories.
o The urban landscape, as cities are transformed (in either planned or unplanned ways)
due to the modification of existing buildings, the creation of new buildings or the
abandonment/demolition of obsolete buildings.
Fragmentation: If alternative employment or new job categories do not emerge to replace
the ones lost to computerisation or adequate re-training (social infrastructure) is not made
available, then society could fragment into sections that have the skills and capital to exploit
the new technologies and those that do not.
Urbanisation: Well-being is a complex concept that includes job satisfaction, a good work-
life balance, stimulation of the mind, interaction with nature, health, wealth and happiness.
As urbanisation increases due to economic and population growth and the stresses of living
and working in cities rises, individual and societal well-being is in danger of being
undermined.
33
Green spaces: as infrastructure develops to meet the needs of cities, natural spaces, such as
parks, gardens and playing fields are in danger of being lost to buildings, roads and
pavements. A positive relationship between green outdoor spaces and levels of stress in the
workplace has been found (Lottrup et al 2013). The well-being of the occupants of buildings
will suffer with a decline in natural spaces. This will result in reduced performance at work,
increased signs of ill-health, such as absence from work, an increase in sickness levels,
reduced retention rates for good staff and a higher turnover. This will have an adverse
economic effect to employers, who will have to compensate for reduced productivity and
output.
Opportunities
Adaptability: Intelligent buildings should be designed to be adaptable and reconfigurable, so
that they can meet the challenges of changing work patterns, but intelligent infrastructure
presents important opportunities for bridging the gap. For instance, heat networks can
provide thermal energy to buildings, but if the energy usage changes with work patterns, then
adjustments can be made at the infrastructure level, saving investment costs in individual
building HVAC plant.
Better jobs: Many of the repetitive, tedious, physical and mentally stressful jobs currently
carried out by people will be computerised, enabling many to pursue more interesting careers,
thus enhancing personal well-being.
New jobs: New employment opportunities will be created by computerisation, which may
more than offset the jobs lost.
Economic growth: cities are engines of economic growth (80% of global GDP) due to the
concentration of diverse pools of labour and the ability of people and businesses to share
information and knowledge (UN DESA, 2015).
Economies of scale: investment in physical (roads, pipelines, cables) and social infrastructure
(education and health) is more effective in cities than in rural areas due to economies of scale
(UN DESA, 2015).
Green spaces: as infrastructure develops to meet the needs of cities, natural spaces, such as
parks, gardens and playing fields are in danger of being lost to buildings, roads and
pavements. A positive relationship between green outdoor spaces and levels of stress in the
workplace has been found (Lottrup et al 2013). The well-being of the occupants of buildings
will suffer with a decline in natural spaces. This will result in reduced performance at work,
increased signs of ill-health, such as absence from work, an increase in sickness levels,
reduced retention rates for good staff and a higher turnover. This will have an adverse
economic effect to employers, who will have to compensate for reduced productivity and
output.
Health: As urban population density and GDP increases, energy consumption, water demand
and transport use will increase. The health, safety and well-being of people, especially
vulnerable sections of society such as children, the elderly and people with underlying health
conditions will be harmed due to increases in pollution, emissions and inadequate sanitation.
The infrastructure connecting buildings to its services will need to balance the demand for
services with the needs of people for good health.
Commuting: Computerisation may reduce the need for commuting as more people may be
able to and be happy to work from home or in non-office environments.

Smart infrastructure
Challenges
Security concerns: vast quantities of data are shared between buildings and networks, so
systems are vulnerable to cyber-attack. Encryption and other security measures ensure that
most transactions are safe and secure, but weak points can be exploited that allow access to
sensitive data and leaving individuals or organisations vulnerable to attack. Financial
resources, intellectual property and organisational security can be compromised.
High initial costs: infrastructure requires physical (or virtual) connections between buildings,
networks and suppliers, so costs of installation in laying cables, pipework and ducting may
be substantial.
Fear of obsolescence: information technology and smart devices are developed rapidly, but
often superseded or upgraded in relatively short periods of time. Therefore, there are fears
that investment in “intelligent infrastructure” or other “smart” technologies may be a waste
of money as the technologies become obsolete.
Disconnect between user and the technology: pervasive computing, in which user friendly
interfaces, such as voice recognition software and virtual assistants, are removing the barriers
between users and services to produce a seamless, intuitive environment. As users become
less familiar with the way that the underlying technology is operating, they will be less aware
of potential problems. Users will then be relying on regulating authorities or experts to hold
the technology operators to account.
Interoperability: vast volumes of data are processed from a wide variety of sources, with
different software and communication protocols. If sources and networks cannot
communicate, then AI will be less effective. Many organisations at the forefront of AI
development use proprietary systems that are not interoperable with other systems.
Privacy: as data are constantly being generated and analysed from intelligent buildings,
intelligent infrastructure and the people that use them, there are many concerns that personal
and organisational information that is currently protected by privacy laws will be available
to third parties, whether they be employers, governments, political organisations, advertisers
or criminals. If individuals or organisations do not have confidence that the data generated
will be used responsibly, then there will be resistance to the take up of smart devices, which
in turn will reduce the effectiveness of the system.
Personalised services: AI and data analytics now have the ability to create personal profiles
from the data generated, which can help companies to target advertising to specific groups
and provide information on political and social interests to lobbyists and polling
organisations. Many of the services provided are useful and benign, but many could infringe
on people’s right to privacy. Balancing the right of data analytics organisations to masses of
data and the right of an individual or an organisation to privacy is a vitally important
challenge.
Disruption: Internet enabled sensors and devices are becoming part of the ICT ecosystem.
These devices are increasingly being used to facilitate distributed denial of service (DDoS)
attacks, in which malicious actors flood a target with service requests to overload the system
in order to disrupt or to extort. Many of the devices in the near future will be wireless micro-
devices embedded in infrastructure, with minimal security protection, so as the networks
expand they will be more vulnerable to attack.
35
Opportunities
Efficiency: intelligent distribution and use of resources through ICT, AI and complexity
modelling will enhance the efficiency of systems, make better use of existing infrastructure
and reduce the need for additional infrastructure.
Flexibility: data mining and deep learning at an infrastructure level enable AI to predict
supplies and demands and respond quickly to any variations. This is especially important as
more renewable energy supplies become part of the supply mix or buildings become energy
producers as well as consumers.
Transparency: intelligent infrastructure, such as smart grids, involves two way flows of
communication between buildings and the network. Users can monitor resource use and
modify behaviour to reduce consumption or save money and suppliers can monitor usage and
modify tariffs or incentives to better manage resource use.
High quality: networks take the strain of peaks and troughs in demand of both consumer and
supplier.
Resilience: intelligent infrastructure can take the strain during extreme events.
Environmentally friendly: intelligent energy infrastructure (electrical energy and heat) allows
us to manage a wide variety of primary energy sources. If we want to reduce carbon emissions
and increase the utilisation of renewable energy, then the infrastructure will enable us to meet
these objectives.
Environmental infrastructure
Energy
Challenges
Building energy consumption: as the number of buildings increases with population and
economic growth, electrical energy demand will grow, which will cause high power system
loading on existing infrastructure and result in overstressed equipment.
Thermal demand: approximately 50% of a building’s energy use (Ürge-Vorsatz, et al, 2015)
is from thermal demand, such as for space heating, cooling and hot water provision. The
majority is provided by fossil fuels such as coal, natural gas and oil. In developing countries
of South East Asia, cooling demand at present is up to 70% of total thermal demand and
consumption will increase significantly as cities expand. As people become wealthier, they
will demand modern facilities such as air conditioning.
New consumers: demand will increase not just due to the increase in the urban population,
but because of technological advances in such areas as transportation (electric vehicles and
urban public transport), data handling (telecommunication hubs, data centres and server
buildings), and robotics (automation of tasks currently carried out by people).
Urban heat island effect: the growth of cities and an increasing population density will cause
ambient temperatures in cities to increase in comparison to the surrounding areas (the heat
island effect). Even without factoring in increasing temperatures due to global warming, there
will be increasing instances of heat waves, which can cause heat exhaustion and heat stroke,
leading to an increase in illness and mortality in vulnerable sections of society. Building
energy consumption will increase to counteract the heat island effect due to the demand for
building air conditioning, which will result in overloading of the electrical network. Current
practice is to bring on low efficiency, highly polluting stand-by plants and ration supplies
(rolling power cuts, charges to discourage use, incentives to encourage use at off-peak times)
at peak times or during heat waves.
Renewables: Figure 4 shows the share of global demand met by renewables at present and
by 2040 in the new policies and the 450 scenarios (IEA, 2016a). As renewable energy
increases in capacity and share of global demand, the infrastructure will need to be able to
manage the intermittent and fluctuating output.
36
Figure 6.4. Share of global demand met by renewables in selected sectors in new policies and
450 scenarios (IEA, 2016a).
Micro-generation (<50kW): buildings will increasingly be electrical generators as well as
users, though expansion of micro-generation systems such as solar photovoltaics, wind
turbines, combined heat and power (CHP) and micro-CHP systems. The network will need
to be able to manage the variable nature of supply and demand between individual buildings
and the infrastructure.
Opportunities
Building consumption: innovations in intelligent building technologies are reducing
electrical energy consumption in traditional areas such as lighting and high performance
glazing and facades, but most buildings consume more energy than predicted, therefore
there are opportunities to reduce energy consumption further by improved prediction and
control. Complexity modelling and deep learning are emerging technologies that involve
data mining, analysis, forecasting and prediction using AI algorithms. The data mining will
not be limited to the analysis of individual buildings, but will encompass the gathering of a
wide variety of information from different parts of the infrastructure connecting the
building, its occupants and its surroundings.
Thermal demand: In 2008 heat losses of the EU27 energy system before end use were
39.3EJ, around 19EJ were from electricity generating power stations and so were not
recoverable, but the remainder (29EJ) was considerably more than the demand of around
11 EJ (Andrews, et al, 2012). In large urban conurbations and cities, district heating and
cooling (DHC) could play a major role in increasing energy efficiency, by using waste heat
from electrical power generation plants and waste incinerators for thermal demand, utilising
low grade heat sources that would otherwise be wasted (industrial processes), utilising
renewable and low carbon heat (solar thermal, biomass, geothermal), reducing the need for
electrically powered cold thermal demand (compression chillers) by using heat driven
absorption chillers, heat pumps and free cooling (rivers, sea water, aquifers). DHC
infrastructure usually includes means of thermal storage, and so peaks and troughs of
demand from buildings can be managed within the DHC network. AI can be used in DHC
networks to optimise the performance of individual buildings and the overall network.
37
New consumers: Electric vehicles such as cars and buses will require additional electricity
capacity, but could be used as short term electricity storage systems in buildings. Intelligent
infrastructure requires more storage capacity to manage supply and demand and so electric
vehicles could help to manage the system. Data centres are emerging as major electrical
energy consumers and carbon dioxide emitters due to the need for cooling. Developments
in low temperature DHC will enable the low grade heat generated from data centres to be
used, whilst at the same time reducing electrical energy demand.
Urban heat island: Intelligent buildings could play a role in tackling the problems, such as
developing green roofs, facades and building envelopes that selectively absorb/reflect solar
radiation to reduce the effect, but buildings themselves could not solve the problem. It will
require the infrastructure of the city or district to be modified, so that there is a balance
between highly absorptive structures such as buildings, roads and pavements and green
spaces, heat refuges and shelters.
Renewables: renewable energy systems requires intelligent infrastructure that can accept
the intermittent and variable nature of the output and a robust and resilient network to
manage the flows. As renewable energy generation grows from a small contribution to
dominating the energy supplies, intelligent infrastructure will need to develop innovative
energy storage systems. Energy storage could take the form of electrical (batteries) thermal
(hot water or ice), mechanical (flywheels/compressed air), chemical (salt hydrates) or
electro-chemical (batteries/ fuel cells).
Micro-generation: Buildings with integrated renewable energy systems will increasingly
be developed in the coming years, and there are many advantages to generating renewable
electricity and heat at a building level. Solar and wind act on buildings whether we utilise
the energy or not, so it makes sense to extract some of the energy if it is practically and
economically feasible to do so. Buildings can reduce their utility bills, or can gain a revenue
stream by selling any excess. Management of the fluctuating and variable supplies will be
challenging to the electrical network, and so energy storage will need to be integrated into
the electricity infrastructure.
Water
Challenges
Demand: A large share of the water (up to 90%) withdrawn by households and services in
high per capita use areas (developed countries such as the North America and Europe) is
returned as wastewater, which requires treatment and energy consumption. The majority of
water withdrawn in the municipal sector is for non-personal use, such as flushing toilets,
washing dishes and clothes, watering lawns and washing cars (Cosgrove and Rijsberman,
2000).
Urbanisation: Urbanisation is projected to grow from one-third urban in 1950 to two-thirds
urban in 2050 (UN DESA, 2015). The water/energy infrastructure will need to be
maintained and expanded to meet the growth in demand for clean water and the provision
of sanitation.
Environment: All uses of water cause some level of pollution, which needs to be treated
before it can be reused. Less than 100% of pollutants are removed because of prohibitive
costs, so some remain in the water or accumulate in the soil. In developing countries, the
provision of sanitation is not keeping up with population growth, resulting in increases in
pollution of water and the aquatic environment.
Health: If water services do not keep up with demand in rapidly expanding urban areas,
then this will lead to an increase in water-related diseases and deaths (3.4 million deaths
due to waterborne diseases in 1998 (WHO, 1999)).
38
Unplanned development: Rapid and unplanned urbanisation in developing countries has led
to the expansion of slums or informal settlements (one third of all urban residents in
developing countries live in informal settlements (UN DESA, 2015), and will continue to
pose health risks and impede the life chances of people due to the lack of access to clean
water and sanitation.
Conflict: Transboundary river basins account for around 60% of all freshwater flow and
supplies around 40% of the world’s population (IEA, 2016b). Management and use from
one location can affect downstream locations, thus creating potential tensions between
states.
Opportunities
Energy efficiency: Increases in the efficiency of energy production and power generation
systems will reduce withdrawals and demand for water. This in turn will reduce the need
for water treatment. CHP and waste heat recovery systems linked though DHC networks
can also improve the efficiency of the power and heat supply infrastructure.
Waste-water recovery: Energy recovery from wastewater could provide opportunities to
improve the efficiency of the water treatment process.
Embodied energy: There are opportunities to exploit the embodied energy in waste-water
by generating electricity from biogas.
6.3 Future scenarios
Energy
Global economic growth is set to more than double over the next 20 years and energy demand and
CO2 emissions are set to increase alongside. Figure 3 (IEA, 2016a) shows the trends in three
scenarios, current policies, new policies (taking account of broad policy commitments and plans
that have been announced by countries) and 450 scenario policies (an energy pathway consistent
with the goal of limiting the global increase in temperature to 2°C by limiting concentration of
greenhouse gases in the atmosphere to around 450 parts per million of CO2). In new policies
scenarios, energy demand CO2 emissions are still set to increase and in the 450 scenario, energy
demand is projected to flatten out and CO2 emissions are set to decrease.
Figure 6.3. Global GDP, energy demand and CO2 emissions trajectories by scenario (IEA,
2016a).
Buildings are responsible for over 40% of energy consumption and 33% of carbon dioxide
emissions (IEA, 2016a). As over half of the population of the planet now live in cities (UN DESA,
2015), and cities become more densely populated, meeting the demand of a growing and wealthier
39
population requires drastic action to mitigate and reduce the effect on the environment and
resources and to better utilise renewable and low carbon resources.
Water
Water is an abundant resource, but only about 2.5% of it is freshwater. Of that, less than 1% is
available for human use, as almost 70% is held in glaciers and ice, and roughly 30 % is deep
underground or unsuitable for human consumption. Most of the supply is from surface water and
groundwater sources, with global freshwater withdrawals increasing by around 1% per year since
the 1980s. The withdrawal rate is outpacing the recharge rates by 1-2% per year globally, therefore
groundwater sources are diminishing and becoming more vulnerable to seawater intrusion.
Agriculture is the main cause of withdrawals and water consumption. The municipal sector
accounts for 13% of withdrawals and 5% of consumption, the energy sector (power generation and
primary energy production) accounts for 10% of withdrawals and 3% of consumption, whilst the
industrial sector accounts for 12% of withdrawals and 8% of consumption. It is projected that
withdrawals to meet municipal demand will increase 17% by 2040, withdrawals to meet industrial
demand are projected to remain approximately the same (8-9%), and withdrawals in the energy
sector are expected to rise by around 2% by 2040, but consumption is expected to rise by almost
60% (IEA, 2016b).
6.4 Development strategy
The development strategy for both intelligent buildings and the intelligent infrastructure that
serves them should aim to integrate the social, the smart and the environmental aspects
holistically. Concentrating on one aspect at the neglect of others may deliver some positive
outcomes, but will not provide modern, efficient, cost effective, profitable, sustainable and
pleasant environments in which people live and work.
Specific topics for consideration.
Well-being
Most buildings are designed to be occupied by human beings, but well-being is often low on the
priority list, if considered at all. Well-being can be enhanced though the design of a space, and the
consideration of human physiology and physiology, but if occupations are stressful or unfulfilling
then well-being can be seriously undermined. There will always be occupations that can undermine
well-being, and stressful or unfulfilling jobs will always be with us, but intelligent social
infrastructure can create urban spaces that mitigate some of the negative effects and make work
more productive.
Hard and soft infrastructure
A balance must be found between hard and soft infrastructure. We define hard infrastructure as
that which consists of concrete, glass and steel buildings, roads, pavements, plazas, and soft
infrastructure as that which consists of parks, gardens, wildlife corridors, green roofs, water
features.
A concentration on hard infrastructure contributes to overheating of cities in summer, which leads
to higher energy consumption, an increase in pollution and carbon emissions, and impacts on
human health and mortality. From an environmental point of view, soft infrastructure provides
shelters from heat and cool spots, it can reduce the overall heat island effect, it also absorbs carbon
dioxide and releases oxygen and water vapour into the atmosphere. It is now widely recognised
that people respond positively to a connection with nature, whether that is for leisure or work, so
that health and well-being can be enhanced (assuming that work-life balance and satisfaction can
be achieved), improving motivation and productivity, whilst reducing costs.
A balance between hard and soft infrastructure can be developed using many emerging techniques
40
such as constructal theory, fractal geometry, evolutionary algorithms, data mining and machine
learning.
Distributed energy
Cities and megacities consume vast quantities of energy due to their high urban density, but this
concentration of buildings and people presents opportunities for distributed energy systems due to
economies of scale.
District heating and cooling networks (DHC)
Cities are increasingly turning to DHC to provide heating and cooling that is potentially more
energy efficient, can reduce carbon dioxide emissions and enables more flexibility at a building
level. DHC have traditionally been driven by combined heat and power (CHP) systems that are
fuelled by fossil fuels, but renewable heat can be integrated as well as providing a variety of fairly
simple energy storage methods (including hot water, steam, molten salt, phase change materials
(PCMs)). Cooling to data centres and server farms, cloud computing factories is increasingly being
sited in northern regions to take advantage of natural cooling from lakes and rivers.
DHC generate data which can be used to optimise delivery of heat as well as minimising energy
consumption and maximising the use of renewable heat.
Renewable energy
It is important that renewable and low carbon energy systems are integrated into a city’s buildings
and infrastructure. Just placing solar panels or wind turbines on roofs may not help in providing
energy to cities, so it is important that the siting and orientation of such systems are optimised. It
may be impracticable to install a system on one particular building, because of layout, orientation
or location, but be practicable on another building. A distributed network at an infrastructure level
would maximise the production of renewable energy, whilst making the overall system more cost
effective.
Water-energy
We are surrounded by water, but very little of it is available for human use. We need to be much
more thoughtful about our use of water. Most of the water is for non-human consumption, but we
extract it from aquafers or reservoirs (which mainly come from run-off), treat it to a standard
suitable for human consumption and pump it to cities. Non-potable water can be recycled for use
close to the customer. Economies of scale mean that cites should re-use most of the water
consumed, reducing the need for fresh water and the energy required to process and deliver it.
Sustainable cities
Sustainable development is most commonly defined as that which “meets the needs of the present
without compromising the ability of future generations to meet their own needs” (WCED, 1987).
Buildings and urban infrastructure are a major cause of unsustainable development, but one of the
easiest to fix, whether it is modifying existing buildings and infrastructure or developing buildings
and infrastructure that are closer to the definition of sustainable development. It is not “rocket
science”. It is not necessary to invent new materials, design new machines or develop new fuels to
design sustainable spaces, although innovations can feed into the solutions and make a difference.
It is a mainly a matter of creative design. Therefore, architects, engineers and urban designers play
the most crucial role in developing intelligent buildings and infrastructure, an example of intelligent
social infrastructure. If these important professions work together from concept to handover, then
they will be more successful in achieving their goals, and be more sustainable, should this be one
of their goals. If these professions work separately or development is linear
(concept/structure/services/control/facilities management) then success is less likely.
Smart cities
The emergence of smart technologies such as robotics, AI, data mining and manipulation, and
41
pervasive computing has great potential to improve the lives and prosperity of citizens but has
many downsides, as described in the state-of-the- art review. A development strategy for intelligent
buildings should embrace the emerging technologies, but mitigate the negative effects. Cities are
great engines of economic development, but as employment patterns and occupation categories
change, it is the responsibility of its governors to act in the interests of its citizens to ensure that
they benefit from the opportunities. Each city or urban space will have different ways of balancing
the benefits and costs of the development of smart technologies, but if only a small proportion of
its citizens benefit from the changes then social unrest will result. Cities are places of growth, but
also places of protest and revolution.
Megacities
There are over a twenty megacities with populations exceeding 10 million people, and most of
them are in developing regions of the world. This report focusses on how intelligent buildings and
its infrastructure can produce a better world for the people living and working in it, whether it is
employment, health and well-being, sustainable development, or technologies that connect people
and improve services. However out focus tends to fall on modern cities in the developed world that
have a civic infrastructure that tends to reduce the inequalities that arise when there are few checks
and balances. In developing regions, where civic society is less well established, informal
settlements are common and tolerated. It is important that advances in buildings and infrastructure
are applicable to developing countries and the outcomes can reduce the prevalence of slums, tackle
poverty and improve the life chances of people living on the margins of society.
6.5 Research Contribution
The research community can contribute to the advancement of intelligent buildings and
infrastructure by gaining a better understanding of the interface between social, smart and
environmental infrastructure.
Research at the interface between social, smart and environmental infrastructure should aim to;
Gain a better understanding of the relationship between changing work patterns and
health, well-being and productivity with respect to buildings and infrastructure.
Develop techniques investigating the relationship between hard and soft infrastructure on
health, well-being and productivity.
Understand the life-cycle costs of intelligent buildings and infrastructure, using a range of
scenarios.
Develop strategies for optimizing hard and soft infrastructure.
Develop models and methods for integrating distributed energy infrastructure.
Develop techniques for optimizing distributed energy infrastructure using techniques
including data analytics, constructal theory, fractal and evolutionary algorithms.
Develop systems and infrastructure that integrates water and energy systems.
Develop working methods that encourage teamwork across disciplines.
Develop systems that integrate smart technologies (big data, AI, IoT, robotics) between
buildings and infrastructure.
Provide solutions that are practical and affordable, so that they can be applied to
developing regions.
6.6 Research Agenda
Researchers need to work across disciplines to develop new thinking, so that everyone benefits
from advances in intelligent buildings and infrastructure. We will need contributions from the
scientific community and from the humanities. If we are to create buildings that serve the people
42
working and living in them then physiological, physiological and social aspects will need to be
addressed as well as the scientific and technical.
The future direction of research in intelligent buildings and infrastructure should focus on:
Developing working methods that encourage team working between different disciplines from the
concept stage. It should be recognised that non-technical disciplines are important to the
development of intelligent buildings and infrastructure.
Ensuring that building owners and occupants benefit from development.
Ensuring that the wider community benefits from development.
Ensuring that advances in intelligent building and infrastructure is accessible and cost effective to
developing regions.
Where possible, water and energy services development should be integrated.
Sustainability must be a high priority, but this must be balanced with the need of building occupants
(health and well-being) and building owners (payback times, life cycle costs).
Smart technologies should be embraced, so that the benefits that they bring can be realised, but this
must not be at the expense of personal liberty or privacy. Transparency is vitally important, so that
data that is being accessed and manipulated is with the consent or knowledge of the individual or
organisation.

7. Sustainable urban transportation in intelligent cities
Xingxing Zhang
7.1 Air quality in underground built environment
Background and Description
Millions of people in metropolis benefit from the convenience of underground systems, which
reduce the traffic congestion above the ground. However, during the recent large-scale proceeding
of urbanization of developing countries, like China, the underground traffic has raised significant
issues ever to the large-and-medium sized cities. One of the severe problems is indoor air quality
(IAQ) in underground systems due to heavy use and overcrowding, unsustainable operation in
public transportation and etc.
Most underground systems are designed as confined space where air pollutants are generated and
diffused as well as enter from outside atmosphere. Hence, various types of air pollutants which
bring threats to human’s health are accumulated in underground systems. IAQ must be a matter of
great concern because regular passages passengers and underground working staff spend
considerable time in the underground system daily. Therefore, in order to ensure the passages
passengers and underground working staff health, relative researches and implements are necessary
for controlling the hazardous air pollutants in the underground system.
Recently, a few studies have been reported to monitor the IAQ and propose strategies to mitigate
this issue. Inhalable particulate matter (PM) concentrations are typically much higher than those
above ground according to some published studies, nonetheless, the substantial factors impacting
the production and shape of PM are heterogeneous that rarely illustrated solitarily yet. The
geographical areas, indicated in Fig. 7.1, discussed include Montreal (Boudia et al., 2006), New
York (Ruzmyn et al., 2015), Los Angeles (Kam et al., 2011), Paris (Bachoual et al., 2007; Tokarek
and Bernis et al., 2010), Mexico city (Hernandez-Castillo et al.,2014; Mugica et al., 2012; Gomez-
Perales et al., 2004), Shanghai (Li et al., 2012; Huan et al., 2014), Beijing (Jing et al., 2012),
Guangzhou (Chan et al., 2002), Xi’an (Gao et al., 2015), Suzhou (Cao et al., 2017), Tianjin (Wang
et al., 2016), Taipei (Kam et al., 2011), Seoul (Son et al., 2012; Kim et al., 2008), Fukuoka(
Chang-Jin et al., 2012), Tehran (Hosein et al., 2014), Puna (Delbari et al., 2016), Istanbul (Sahin
et al., 2012), Bracelona (Moreno et al., 2014), Stockholm (Klara et al., 2012), Helsinki (Aarnio et
al., 2005), Milan (Colombi et al., 2013), Rome (Perrino et al., 2015) London (Pakbin et al., 2010;
Adams et al., 2001) and Birmingham (Harrison et al., 1997). The majority of this research was
conducted via on-site testing of PM at different sites in the subway stations, i.e. the station hall,
carriages etc., with corresponding analysis on the distribution and physicochemical properties of
PM2.5 in each location in the subway station. For instance, Kam et (2012) measured the
concentration of the particles in six different cities for eight years in eastern of America. Then they
analyzed the correlation between death rates and the particles and they found that correlation
between mortality and the PM2.5 was strong. Delbari et al (2017) reported that the mortality would
increase 1.5% when the average concentration of the PM2.5 increases 10 μg/m3, Pope C et al (2002)
also got similar results. Moreover, some researchers have reported that the concentration of
particles in the subway were much more than the outside environment and they were much more
gene toxic which could cause more healthy problems to public (Kijnzli, Kaiser et al. 2000, Guo,
Hu et al. 2014). Now there are many studies, which measured the particles in public transportation
including the Metro, buses and so on (Adams, Nieuwenhuijsen et al. 2001, Cheng, Lin et al. 2008,
Cheng and Yan 2011, Kam, Cheung et al. 2011, Cheng, Liu et al. 2012). In these studies, the factors
45
influencing concentration and distribution of PM in subway stations include seasons, weather, time,
traffic density, brake system, ventilation system, passenger density, depth, design, aboveground or
underground, operating duration, location, piston effect, outdoor traffic (Park et al., 2008, Li et al.,
2012, Cheng et al., 2008, Hernandez-Castillo CR et al., 2014, Moreno et al., 2014, Midander et
al., 2012, Aarnio et al., 2005, Boudia et al., 2006). And the measured targets or components in
subway stations were outdoor climate conditions, platforms, passenger carriages, driver
compartments, station offices, rest areas, ticket offices, station precincts (Li et al., 2012, Hosein et
al., 2014, Park et al., 2008, Huan et al., 2014, Ruzmyn et al.,2015, Kim et al., 2008, Cheng et al.
2008, Moreno et al., 2014, Midander et al., 2012, Kim et al., 2014, Aarni et al., 2005).
Figure 7.1 Geographical locations of research into PM2.5 in subways
According above studies, it is likely that the PM analytical results would be different if the
studies were performed in another country or even in the same city, as the influencing factors and
the measured targets/components may vary. To make an accurate assessment, it is necessary to
carry out the local measurement and analysis. Besides the PM, coeval concentrations of COX,
SOX and NOX are also significant sectors that should be investigated on underground train station
platforms.
Sampling and observation are the primary method currently used for the physical and chemical
characterization of IAQ in subways. The main physicochemical properties are: (1) the shape of
pollutants in subways is complex and changeable; there are no stable or identical shapes identified;
(2) current research focuses mainly on the elementary composition of pollutants; these chemical
are not found as individual elements but as part of a compound. Current research demonstrates that
the factors influencing the concentration and distribution of pollutants in subways included
external, internal, human and operational factors. Pollutants sources in subways are usually divided
into two categories: from the external outdoor environment and from the subway interior i.e. the
perennial equipment, the ventilation systems and the train brake systems. The control strategy of
pollutants relies on the features of the subway. In contrast to buildings over-ground, subway
stations could be considered to be "semi open construction" and therefore obviously affected by
the outdoor environment. IAQ in subway stations is dependent on the ventilation system with the
control strategy provided by most of researchers being through prevention and control through
ventilation. Although subway cabin air purifier (SCAP) has been used in subway carriages to
46
reduce pollutants concentration, there is still a lack of definite methods for the control of platform
and station hall ventilation systems.
Objectives
This road map aims to bring forward the urgency and necessary of mitigating the IAQ problem
in underground built environment. It seeks to advance the understanding of indoor air pollutants
and pertinent measures which save energy consumption, enhanced the IAQ level, and minimize
the health risk in underground, by consolidating a large set of new peer-reviewed work that
highlights the implement in the IAQ improvement and sustainable operation in underground
system for future intelligent cities.
Future research potential topics may include, but are not limited to:
• IAQ in underground and suspended particulate matter
• IAQ in underground and source of air pollutants
• IAQ in underground and mortality risk reduction
• IAQ in underground and season dependent model
• IAQ in underground and thermal comfort
• IAQ in underground and energy saving
• IAQ in underground and ventilation system
• IAQ in underground and online monitoring
• IAQ in underground and numerical simulation
• IAQ in underground and sustainable operation
Focus of research and development
Systematic research method: sampling and observation is the primary method currently for the
physical and chemical characterization of air quality in underground built environments. Due to
the complexity of undergrounds, many people are sceptical about the accuracy of results and
validity of data. Further research into the theory and methodology must be completed to improve
data analysis.
Characterized measurement locations and long-term data collection: most of the existing
studies focus only on a certain area or a certain underground so that the research results may have
significant differences due to many varying factors. The characterized measurement locations in
undergrounds need to be defined and made uniform, such as carriages, work areas, public areas
(platform, station hall) and outdoor environment. Since the main analysis method used is
sampling and observation, large accumulations of data will be required, which must be achieved
through long-term measurements in underground built environments.
R&D in different locations and scenarios: The factors influencing the IAQ in undergrounds are
different from locations and scenarios. It is very likely that the IAQ would be different if the
studies are performed in another country or even in the same city. To make an accurate
assessment, it is necessary to carry out the local measurement and build local database for
analysis.
Control against energy saving: some researchers have argued from an energy-saving
perspective that air only needs to be controlled within the carriage since passengers spend most
time there. It has been suggested that underground air-conditioning and ventilation should be in
47
mind from the very beginning of design up to final operation so as to control air distribution in
undergrounds whilst consuming as little energy as possible.
Millions of people in metropolis benefit from the convenience of underground systems, which
reduce the traffic congestion above the ground. However, during the recent large-scale
proceeding of urbanization of developing countries, like China, the underground traffic has
raised significant issues ever to the large-and-medium sized cities. One of the severe problems
is indoor air quality (IAQ) in underground systems due to heavy use and overcrowding,
unsustainable operation in public transportation and etc. Most underground systems are designed
as confined space where air pollutants are generated and diffused as well as enter from outside
atmosphere. Hence, various types of air pollutants which bring threats to human’s health are
accumulated in underground systems. IAQ must be a matter of great concern because regular
passages passengers and underground working staff spend considerable time in the underground
system daily. Therefore, in order to ensure the passages passengers and underground working
staff health, relative researches and implements are necessary for controlling the hazardous air
pollutants in the underground system. This road map aims to bring forward the urgency and the
needs of mitigating the IAQ problem in underground built environment, especially at subway
stations. It seeks to advance the understanding of indoor air pollutants and pertinent measures
which save energy consumption, enhanced the IAQ level, and minimize the health risk in
underground, by consolidating a large set of new peer-reviewed work that highlights the
implement in the IAQ improvement and sustainable operation in underground system for future
intelligent cities.

8. Keeping Abreast with Technology
Eva D'Souza
In order to get the most out of the technology you have and to compete in the business world one
has to keep abreast of emerging new technology. You deal with the technology for your personal
use, at home, at work and wherever you go to connect with people and places and to deliver the
work tasks. Technology is changing rapidly and to keep pace with it is not an easy task.
Having a technology awareness strategy should ease the pressure in keeping up to date with the
technology. Some of the following factors should help in developing the strategy:
List your requirements: Defining and developing specification what you want to deliver is
very important.
Define the period: Once you specify the project, defining the life span of various
elements is essential
Available resources: Engaging right resources and making sure the technology fit for
purpose is the foremost
Resilience: Any technology you use make sure it is robust and will sustain for the whole
life cycle of the project
Infrastructure: Choosing the right infrastructure to adopt technical changes, operating and
maintaining and recycling techniques to meet the financial targets.
Looking forward:
We are losing the track of technology and depend more on intelligent systems and loosing human
interaction. The same intelligent pace is not available when something goes wrong.
Intelligent approach to meet the system requirements throughout the project cycle
More reliable products
More technical resources
More intelligent practice in trouble shooting
More cost effective systems

9. Digital Futures
Peter McDermott
9.1 Conceptual Framework
The impact of digital technology and artificial intelligence on business, automation and
communications is transforming the world in many ways. The digital transformation is as
significant as the impact of new technology in the agricultural and industrial revolutions.
In the built environment digital technology continues to have a transformative impact. The
requirements and forms of many types of building, including shops, factories, offices and homes,
are all changing rapidly with the digital revolution. No one is sure where what the destination will
look like. Digital village halls? Smart offices? Pop up shopfront showrooms for digital retailers?
Social hubs? Living pods? Virtual homes? All established building paradigms are being explored
amid a new digital and globalised world. The impacts of climate change and popular unrest
caused by inequality and rapid change in economic distribution reflect a more uncertain future.
The increasing prevalence of digital technology in every facet of modern life has included a
significant impact on buildings. In fact, some would argue that the term “intelligent building”
itself reflects an attempt to define how this innovatory and ubiquitous technology has transformed
buildings and construction in the last thirty years.
From early attempts to automate control of buildings using large mainframe digital computers, to
the current prevalence of distributed digital controls (DDC) in commercial and now increasingly
in domestic buildings, to the redesign of the buildings themselves to reflect the organisational and
increased cooling needs of information and communications technology (ICT), these changes
have been immense.
Moore’s law states that computer power doubles in power every 2 years and even thought this
pace of change is set to slow, the new leaps forward in the field of Artificial Intelligence (AI) will
soon impact design, construction and operation of digital buildings.
9.2 State of the Art
Most buildings currently use DDC to control their mechanical, electrical and public health (MEP)
services. In a typical modern building, small digital computers typically called controllers (DDC),
are distributed throughout the building. They monitor and control the local equipment in order to
achieve the internal conditions and energy performance required by the occupants and legislation.
The digital software applications used in these controllers are normally based on traditional
sequential Boolean logic and three term control loops. Fuzzy logic and machine learning
programmes are very rare.
In larger buildings, these discrete controllers are networked together with a personal computer or
server /client computer system. This provides a human supervisory arrangement usually
implemented by a real time graphical user interface. This networked system is called a Building
Automation and Control System (BACS) or Building Management System (BMS), sometimes a
Building Energy Management System (BEMS). Where the control of the MEP is integrated with
other digital systems in the building such as CCTV, access control, fire alarm systems etc., the
system is often called an integrated Building Management System (iBMS).
9.3 Future Scenarios
Several potential development trajectories for digital control of buildings are apparent.
Commercial market pressure, user preference and security concerns will determine which
52
approach prevails or dominates in the various applications.
Increasing use of cloud computing, where the digital software is hosted in remote data centres,
offers the possibility of building automation as a remote service. Buildings would consist of MEP
equipment with appropriate imbedded networked sensors and actuators. The digital intelligence
will be provided and hosted offsite and delivered via the internet by specialist providers. These
providers could also add value by use of “big data” analytics using machine learning and artificial
intelligence (AI) to optimise the performance of building services. This scenario would offer the
suppliers the benefits of a service type business model and the ongoing revenues associated with
it. For the building owners and users there is the promise of setting business orientated KPIs for
the specialist providers while giving them the freedom to focus on their core business. Whether
this constitutes a virtual Intelligent building or rather a dumber building that is merely a
component of a larger “Intelligent Organisation” is a debatable point. Opening up the building
control devices and networks to the internet offers a huge target and opportunity for malicious
fun for hackers, criminal gangs and state cyber warfare agencies. Cyber security becomes
paramount in preventing a possible panacea for building performance become a Trojan horse for
malevolent action by third parties currently unable to gain access to the buildings and people and
organisation that inhabit them due to traditional and well understood physical security measures.
Another development trajectory for digital control could be the increasing use of packaged MEP
equipment supplied with their own on-board DDC. The software could be optimised by the
manufacturers to the specific applications for the functionality of that packaged equipment. The
data from the packaged digital controls is then merely agglomerated via a standards based open
protocol network to an integrated user interface. This would create a secure integrated building
management system (iBMS) for the building. In this scenario, the building still retains the digital
intelligence and therefore it is, in itself, an Intelligent Building and can operate as such without
the connection to the wider internet and cloud based services Individual equipment suppliers
will monitor and their own specific applications and data can be gathered locally and exported for
external data analysis as required without the security risks of permanent online transparency.
These technology scenarios are a subset of much bigger those societal changes driven by
increasing globalisation, urbanisation, growing wealth in-equality, aging populations, and climate
change. The biggest impacts of digital transformation will be the increasing automation of human
work, the subsequent redundancy facing many tax paying workers but also possibly prefacing
super-abundant production and expansion of leisure time. This will force a paradigm shift in how
society organises itself and distributes the fruits of digital production throughout the human
population. The big question will be that faced only by the very wealthy in the past: What will
we do with our time? And in our field the smaller one “How will this affect our buildings?”
9.4 Development Strategy
Large internet giants like Google and Amazon are following the offsite intelligence scenario as
this plays to their strengths in data centre provision and big data analytics.
The traditional suppliers of BMS and process automation are developing ever more sophisticated
and cost effective products to support DDC or “edge computing” where the digital intelligence is
distributed locally near point of use and retained within the building
9.5 Research Contribution
Academic Research could contribute by developing the basic knowledge of digital controls
theory and application within buildings. Optimisation involves meeting sometimes competing
criteria of occupant comfort, energy use, carbon emissions, and capital cost. Metrics that quantify
53
these parameters and assist the trade-offs optimisation requires can help with decision making.
9.6 Research Agenda
Future academic research could contribute by examining the relative costs of the differing
approached to providing digital automation and control in different applications, markets and
scale of buildings. Research in the better application of data analytics, machine learning and AI
as applied to building performance and optimisation could also be beneficial.
For the bigger digital society picture more research in the market and ownership models of
technology companies and the impact of un-equal income distribution and increase leisure time
on human health and wellbeing would help provide evidence for the ongoing political
deliberations on future economic and social policy.
The impact of digital technology and artificial intelligence on business, automation and
communications is transforming the world in many ways. This digital transformation is as
significant and disruptive as the impact of new technology was in the previous agricultural and
industrial revolutions.
In the built environment digital technology continues to have a transformative impact. In fact,
some would argue that the term “intelligent building” itself reflects an attempt to define how
this innovatory and ubiquitous technology has transformed buildings and construction in the
last thirty years.
From early attempts to automate control of buildings using central mainframe digital
computers, to the current prevalence of distributed digital controls (DDC) in commercial and
increasingly in domestic buildings, from mandatory BIM to the redesign of the buildings
themselves to reflect the needs of ubiquitous information and communications technology
(ICT), these changes have been transformative.
Differing trends in digital control of buildings are apparent. Commercial market pressure, user
preference and security concerns will determine which of these approaches prevails or
dominates in the various applications.
Increasing use of cloud computing, where the digital software is hosted in remote data centres,
offers the possibility of building automation as a remote service.
The traditional suppliers of BMS and process automation are developing ever more
sophisticated and cost-effective products to support DDC or “edge computing” where the
digital intelligence is implemented locally.
Which strategy eventually succeeds will be determined by the developers and users of the built
environment.

10. Upskilling for technology enhanced collaborative working
Tong Yang, Rosangela Tenorio
Building information modelling (BIM) gets people and information working together effectively
and efficiently through a set of interacting policies, processes and technologies (RICS 2014).
BIM implementation has been changing the dynamics & behaviour of the design-construction
supply chain, unlocking new, more efficient & collaborative ways of working. Meanwhile, this
digital platform enables forensic tracking of high-quality information to support business
outcomes through true collaborative effort amongst all stakeholders in the AEC industry (Holzer
2016; Strong & Burrows 2017).
10.1 nD capacity of BIM
Multi-dimensional implementations of BIM enable the integration of knowledge management
systems and empower handling and sharing of digital information during the building’s lifecycle
(B1M 2015). Inclusion of accumulated information to building’s operation phase through nBIM
enables better decision making on design choices for optimal economic, environmental and social
sustainability.
Figure 10.1 Illustration of 6D BIM (B1M 2015)
• 3D: The shared information model in a Common Data Environment (CDE). 3D information
model includes graphical digital prototype of a physical building embedded with non-graphical
information of actual building elements and systems for design analysis, visualization,
optimization, and lastly, project data handover to a client at completion.
• 4D: (3D + time) Construction planning and scheduling visualisations. Project scheduling allows
project team to map timings onto activities, simulate planned work is safely, logically and
efficiently sequenced, ensure proper logistics, space utilisation in the construction phases of the
project.
• 5D: (4D + cost) Cost estimation. The model uses intelligent content objects, various participants
(architects, designers, contractors and owners) can use the model for real-time cost planning and
trade verification. Real BIM objects from manufacturers will make cost calculation more accurate.
• 6D: (5D + operation and maintenance) Project lifecycle information. Owners/Facility managers
55
can use the model or export BIM objects property information to existing FM software to operate
and maintain the building with an integrated view of a built-asset throughout its life cycle, including
constructability, sustainability and future-proofing factors.
10.2 Creative play and collaborative learning
Digital technologies enabled BIM collaborative processes to significantly improve the efficiency
of design, construction and operation, and provide a platform for continuous upskilling for all
(Klaschka 2014; Sanchez et al. 2016). Since the invention of LEGO bricks 60 years ago, it is still
a legendary toy embracing the principles of systematic creativity into educational play. One of
the new comers, ‘littleBits’, a set of interchangeable electronics modular snapping blocks
introduced programming through simple and fun opportunities for creative design in various
cartoon/drama themes (Bdeir 2012). Meanwhile, playful and community engagement learning
activities were designed to create a successful collaborative environment- The Plug in units, that
encourage teamworking and social learning to think, create, operate and maintain buildings and
reuse it sustainably, productively and responsibly (Tenorio et al. 2018).
New generations of AEC students are very familiar with virtual gaming settings and generally
motivated in the teamwork approach assisted by BIM-enabled visualization and information
sharing (Sinclair 2006). Collaborative working is required to break the tradition of working in
silos and sub-optimal work sequences, so the learning and training programmes would be
benefited through multi-disciplinary cross-faculty curriculum planning and management (Jin et
al. 2017) as current changes happening in the industry is depicted in Fig. 10.2 (Bernstein 2015).
Figure 10.2. Collaborative information and knowledge management through a building’s
lifecycle (Bernstein 2015)
10.3 Upskilling and managing changes
As the PESTLE factors (Political, Economic, Socio-cultural, Technological, Legal and
Environmental) that influence all decision-making will be constantly shifting, BIM technology and
processes provide a dynamic integrated learning platform/facility of sharing best practices and new
skillsets (Fig10.3) for AEC workforce (Succar 2009).
56
Figure 10.3. Individual BIM Competency Index (http://www.bimframework.info/competency/)
International standard ISO19650 supports the alignment of BIM standards to get a global industry
working in a consistent and intelligent way. BIM skills learning and development must adapt to
variations of PESTLE in a rapidly evolving industry. Effective change management with inclusive
and open workflow of BIM will anticipate the impacts of emerging disruptive technologies, ever-
more profound integration between information sources through all phases of projects, and
continuously industry wide digital transformation with future-proof skilled workforce.
While universities are facing constant competition to attract students and keeping up pace with
technology changes, the timely tasks for maintenance and renovation of ageing infrastructure with
funding constraints could be the most suitable onsite learning opportunities and challenges for
students. AEC students as the ambassadors of student communities could participate in key
stakeholder groups (project sponsor, end user and project instigator) engagement meetings, are
actively included in the communication process of planning and making technical, design and
management decisions.
In addition to sound digital technology skills, students also need to acquire essential soft skills of
effective cross-disciplinary collaborative working (Llewellyn 2015). Through project-based
experiential learning on BIM implementation from the perspective of the lifecycle of a built asset,
students can communicate with peers, academics, the supply chain, clients, customers and local
government, and delve into best practices in the real-world. Decades of practical lessons learnt
could be categorized and condensed into benchmark case studies through closer academic-
industry collaboration. By producing virtual projects with real client brief for group learning,
students would be encouraged to create ideas, make mistakes through learning-by-doing, and
deliver in line with clear industry requirements and expectations to bridge the performance gap
(iStructE 2017).
Students and staff with their mobiles and IoT devices could be a part of high resolution active
human sensor network for intelligent and sustainable university estate operation. Big data
analytics communicated through AI assistant could attract students to experience the first hand
human-building interaction and occupant behaviour impact on live building performance
dashboard (fig. 10.4). Through informed decision making on which data needs to be tracked over
time for obtaining insight on building performance, students are trained to filter out noise and
junks in the big data cloud and develop their critical thinking skills.

10.4 Open source intelligent buildings and social infrastructure for the future
In our digital age, the open building concept (Kendall 2006) evolved and transformed with latest
smart technology advances, AI enhanced design automation, offsite construction, etc. Futuristic
sustainable intelligent buildings and cities could be realized by nurturing crowd based open source
design and collective social infrastructure creation to improve the quality of life and the well-being
of citizens (Sinclair 2006, Ingels 2016).

11. Wellbeing homes
Pete Halsall
Wellbeing homes are not an entirely new a concept; although for the last 50 years or so this idea
has been more about the avoidance of ill health, rather than the augmentation of health. Clearly
the focus of wellbeing homes now needs to return to how quality and longevity of life can be
enhanced and extended, sustainably, so that people can live longer, happier and more fulfilled
lives, with the wellbeing home as a key instrument for this. Frank Lloyd Wright made big
promises, or at least big assumptions, for how his homes could impact on the quality of lives of
their residents: “ People who live in these advanced houses must have a greater feeling for life,
and be more themselves. It can be very liberating to see so many elements of nature.” Those
designing and developing the wellbeing home must take on this level of confidence and ambition,
applying it to a contemporary setting. We are now in a period of quite extraordinary and
unprecedented change and disruption - with the likelihood in the very near future of autonomous
cars, digital lives, genetically modified babies, extraordinary technology - but what will all of this
mean to how, and where we live, and to the quality of our lives ? At the same time as we race
towards potentially exponential technological development, we are becoming increasing at odds
with both the natural environment, but also potentially with our own nature. Surely a wellbeing
home is one that, fundamentally, seeks to reconcile these increasingly dramatic and opposing
forces so that we really need to live in much more natural and naturalistic environments, being in
touch with and at ease with nature and our own nature, whilst enjoying the fruits of technology
and harnessing hyper change to enhance wellbeing.
Ironically, the first thing that we have to do then is to get people as much out of their homes, as
into them. Estimates vary, but it seems that in the West we now spend up to 90% of our time
indoors; with the unsurprisingly attendant health issues - both psychological and physiological
ensuing; social isolation, insufficient exercise, obesity, increasing dislocation from both nature,
and therefore the corollary of that, an increasing dislocation from our own nature. So, with no
small amount of creative tension, the essence of a wellbeing home must be one which we are
both happy to be in, and at the same time, one which we are happy to not be in. The wellbeing
home must be conceived as one which is as much outdoors as indoors, a lifestyle if you wish that
has both the hardware of bricks and mortar, but also the software of increasingly complex and
imaginative lifestyle choices.
In conceiving of the wellbeing home in a much more flexible way, then we need to think in terms
of living in the city, and only, in part, in our homes. This indeed reflects how many Asian cities
now are; In Seoul in South Korea, birthday parties are held in public parks, not lounges, rooms to
play video games are rented with friends and not always now played in bedrooms, studying is
done in generously sized coffer bar lounges or bookshops; indeed home is the last place that you
go to after work, rather than the first place. So that the effect of all of this is that a wellbeing
home makes no sense if we don’t at the same time have the wellbeing city. Increasingly we
should think of the city as where we live and the home as just one part of an increasingly
complex patchwork of places, services and new ideas yet to be invented. We must then seek and
strive equally for both the wellbeing home as well as the wellbeing city; the whole to be natural,
vibrant, interesting, challenging, sociable, productive, full of multi-sensory experience, beautiful
- and safe, both physically and also digitally, free of crime and cybercrime. Maybe we should
think more about the nuclear family model, which is now sub-optimising how we live - perhaps it
60
is now the ultimate barrier to a more collaborative and sharing based society where we must now
with scarce optimise housing, cities and economics.
Focusing on the wellbeing home as a necessary subset of the necessarily wellbeing based city, we
can see that the environmental aspects, both inside and out, are fundamental. We already know
that our definition of what is functional needs serious re-thinking, and has largely been framed in
the last 150 years around a startling ignorance of our own nature; so that a beautiful and engaging
environment is not something which is nebulas or destroying of efficiency and utility, but rather
something which enhances and optimises our psychological and physiological functioning - thus
increasing utility and efficiency; the ultimate, ‘value added’ experience if you like, but played out
in the everyday with the objective to enhance and extend both quality and longevity of life.
The state of the art for the wellbeing home has to start with high quality architecture, itself,
arguably, the highest of all art because it can contain and contextualise all other art, and indeed
science and technology; this must be the framework and concept around which everything else
functions. Indeed, it was Frank Lloyd Wright who also said “I believe that a house is more of a
home by being a work of art.” Some may say that this is an impossible dream - but the reality of
modern manufacturing and consumerism is that pretty much everything becomes economically
available to the majority, not just the minority of the population, in due course. We have then to
start with economic and development models which free the market and the forces of innovation
to deliver what everybody wants - a beautiful, wellbeing home, in a beautiful, wellbeing city, at
prices that we can all afford. 3D printing and other advanced manufacturing techniques are
making the decorative, the beautiful, the fractal - very readily available, and so there are
increasingly no excuses for a lack of beauty.
From a technological stand point, we are now at a point we were are no longer constrained,
certainly in the same way that we were in the past, by what technology is available - we can co-
create, curate and commission new technologies to serve a plethora of lifestyle and wellbeing
needs around the home. We must mine the huge amount of industrial and academic research to
find new scientific understandings and to create new technological paradigms and specific
solutions. The increasing blurring of what is home, what is housing technology, and what is ‘us’,
rapidly reframes and extends what is possible. Fitbits which measure our skin temperature can be
used to control heating systems - our outward breath can be monitored to set and vary ventilation
controls - in each case room by room. Why not? Remember, the limit of technology, certainly in
its conceptualization, has always been the limit of our imagination.
To accomplish all of this we must as part of creating the wellbeing home and the wellbeing city
take back our democracy and increasingly advocate strongly and determinedly for change at the
city level; for genuine and meaningful citizen participation in city governance. Citizens know
better than the vast majority of designers now, and that is what is beauty is. If we believe that
democracy is worth it, and that it counts, then we should not bat an eye lid. The wellbeing home
and the wellbeing city need to be thought of as key aspects of a sustainable, egalitarian and truly
democratic future; our first job then is to think, to design, to realise phenomena and new concepts
at the socio-economic, and also at the pscyho-political levels, so that we can create the context in
which the wellbeing home can become ubiquitous, by being affordable. In other words if we are
to have the wellbeing home and the wellbeing city then we must first create the political and
economic context in which this can happen.

12 Bioelectromagnetic Design
Isaac Jamieson
12.1 Conceptual framework:
What are we talking about? Game-changing interdisciplinary design/disruptive innovation that
blends cutting edge biological research with technological innovation and international best
practice to create new design paradigms for biologically friendly buildings, technologies and
environments.
Technological innovation
An essential component aiding advancement in the new ‘Bioelectromagnetic Age’ is the creation
of more bioelectromagnetically friendly intelligent and responsive buildings and technologies.
The need for detailed research into how to biologically optimise electromagnetic exposures in the
built environment is long overdue, with rapid progress, development and deployment of effective
(often low cost) technologies and techniques appearing possible in many areas.
This ground breaking initiative is also set to help the building industry better tap into the global
Wellness Market, a trillion dollar industry that is already three times larger than the worldwide
pharmaceutical industry. It represents disruptive innovation at its very best.
Enhancing health and well-being
We are presently experiencing exponential growth in environmental exposures to manmade
electromagnetic phenomena. Often little thought is given to their potential positive or negative
biological effects, a shortfall that can be actively addressed.
It is very important for us to investigate how healthier “next generation” bioelectromagnetic
environments and technologies can be created.
12.2 State of the Art
What are the issues and where are we today?
Numerous studies demonstrate that electromagnetic phenomena can be biologically active.
Knowledge already exists on how we can create healthier environments and this can be readily
built upon.
Bioelectromagnetic health matters
The World Health Organization/International Agency for Research on Cancer already classifies
radiofrequency (RF) electromagnetic fields “as possibly carcinogenic to humans (Group 2B)”.
Some experts suggest RF radiation should be upgraded to Group 2A, ‘probably carcinogenic’, or
even Group 1 ‘carcinogenic’. [Research also indicates that 5G frequencies and other millimeter
wavelengths can be biologically active even at very low intensities].
Mains frequency magnetic fields too are presently classified as group 2B carcinogens
(WHO/IARC 2002), and there is evidence that excess electrostatic charge and mains frequency
electric fields [at levels encounterable in many indoor environments] can, at least indirectly,
negatively impact health. Studies have additionally shown that the types of lighting and glazing
that are specified can have marked biological effects. Again, healthier solutions can be specified
and/or created.
62
Such findings indicate that a strong opportunity exists for the building industry to be better
educated on how to optimise exposures, create “Win/Win situations”, and protect against risk.
There is a need to reduce “electromagnetic pollution”
This present initiative helps address the need to optimise biological performance through
intelligent design and create safe environments for individuals who are electromagnetically
hypersensitive (EHS) or otherwise adversely affected by electromagnetic pollution. It
additionally helps aid productivity, fosters wellbeing, better protects the environment, and creates
fertile ground for bio-friendly innovation.
[As an aside, “electromagnetic pollution” also hampers the effective use of technology. IEEE
SPECTRUM reports electronic noise is drowning out the Internet of Things, and will become a
very expensive problem to deal with unless action is taken now].
Estimates for the number of individuals with EHS vary, with several countries reporting it may
affect between 4-10% of their populations. In the UK alone this would correspond to
approximately 2.5 to 6.3 million people, a number well in excess of the 1-2% of its population
using wheelchairs for which the building industry already makes provisions.
Other members of the community are also considered by some experts to be at higher risk from
exposure. It is our duty to create inclusive environments that minimise / avoid such risks and act
to actively improve wellbeing.
Need to design in inclusivity and wellbeing initiatives into projects
The WELL® Building Standard already takes into account the need for EMF-protected design. It
is becoming increasingly important that we seek to intelligently optimise the electromagnetic
characteristics of our designs to address such matters.
Best practice can help ensure that the environments and technologies we design and/or specify in
this “Bioelectromagnetic Age” aid social cohesion and comply with the United Nations
Sustainable Development Goals (SDGs).
Liability issues
Many insurance companies are now refusing to cover claims linked with electromagnetic
radiation. It is vital that we are in the forefront in addressing such challenges, and use this
occurrence as a springboard for beneficial change and innovation in our industry.
Legal action and ruling issues
There have already been legal actions and rulings won relating to the effects of electromagnetic
pollution. Cases appear likely to greatly increase unless proper proactive measures are put in
place.
Stakeholders
Stakeholders in this issue include: building professionals; medical doctors; members of the
general public (including those who are EHS); scientists; manufacturers; ministries of health;
NGOs; product designers; and technology companies.
‘Win/Win’ situations are possible, and can raise the accomplishments of Intelligent and
Responsive Buildings to a whole new level.
We have a duty to our future selves to develop robust policies and practices that will help
63
continually improve the health and wellbeing of individuals and the environment.
12.3. Future scenario
In 10 years’ time we wish to be in a position where “bioelectromagnetic environmental issues”
are openly addressed in the design of buildings, technologies and environments, with ongoing
best practice involving multiple stakeholders continually seeking to refine and improve measures
taken.
By that time it is intended that many buildings will have biologically optimised “low
anthropogenic EMF zones” (so called “white zones”) as standard, as will the infrastructures that
allow people access to them. Some may also feature special “bioelectromagnetic climates” that
further aid individual wellbeing and performance.
3D EMF design templates
It is envisioned that 3D EMF templates will be used as standard as spatial planning tools to help
reduce individuals’ exposures to “electromagnetic pollution”.
Optimised exposures to electromagnetic phenomena
Exposures to electromagnetic phenomena will be fine-tuned (wherever possible) to aid circadian
rhythms, general biological functioning, and task performance.
The effects of electromagnetic phenomena will be taken into consideration as standard, as will
the need to have key areas and green infrastructures free from “electromagnetic pollution” to help
cater for those who have become sensitive to electromagnetic phenomena, those who wish to live
in more natural electromagnetic environments on a daily basis as a matter of personal choice, and
those wishing to have “digital detoxes”.
It is intended that “white zones” / biologically optimised exposure zones will be provided as
standard in many public spaces including, health centres, hospitals, grocery stores, petrol stations,
libraries, parks, theatres, etc., to permit inclusive design that caters for those who are EHS. It is
also intended that ‘white zones’ will be created within housing developments, workspaces, etc.,
for similar reasons.
It is expected that in 10 years’ time, provision of external low-EMF green space and low-EMF
green corridors will become a design norm as we learn to work more in harmony with nature,
rather than against it, and gain greater understanding of the electromagnetic nature of all life.
Ideally by this time period, all technologies will be transitioning to more bio-friendly versions of
their former selves.
[With proper planning such initiatives can also contribute towards electromagnetic pulse (EMP)
protection. At present little is done to counter such threats in the design of the built environment,
even though they are Tier 1 risks. It is suggested that ≥20% of all developments should be low
EMF and EMP-shielded with on-site power generation. Such provision will significantly improve
national security and resilience].
It is envisioned that bioelectromagnetic design skills and EM shielding skills will be in high
demand.
12.4 Development strategy
Much of what needs to be known to create safer, more “bioelectromagnetically friendly”
64
buildings, environments and technologies is already known. A great deal of this intellectual
challenge is already solved, or provides strong clues as to what areas of investigation need to be
taken to determine the best solutions. The opportunities for game-changing innovation are
virtually endless.
The willingness to open our eyes to the exciting opportunities that exist is all that is required to
take the first step into a brave new future.
12.5 Research Contribution
R&D can make substantial contributions through bringing together and linking knowledge and
best practice from all around the world on areas that can impact “bioelectromagnetic health”. It
can also be of tremendous service in testing theories and refining what is already known. It is
predicted that funding such areas will provide a sound return on investment for those interested in
creating a more bio-friendly world.
12.6 Research Agenda
The worldwide research agenda is to assemble interdisciplinary teams of renowned experts and
suitably qualified additional stakeholders to blend cutting-edge biological research with
technological innovation, international best practice and “real world” needs.
Work required includes detailed investigation of the potential beneficial and detrimental effects
of exposures to a wide variety of electromagnetic phenomena, and best practice standards that
exist to date. Luckily much initial work in these areas has been undertaken and it provides us
with indications of what is required to progress still further with good chances of success.
It is envisaged that such a wide-scale interdisciplinary international effort will reveal numerous
potential technical breakthroughs and best practice improvements that can substantially enhance
the design and operation of intelligent and responsive buildings. With the air of openness and
international unity being encouraged for this topic, and the great breakthroughs that are likely, it
is envisaged that cooperation between research and practice will be high.
The ‘Win/Win’ situations that are achievable can raise the abilities and performance
characteristics of Intelligent and Responsive Buildings to a whole new level. They can also
change the face of technology as we know it. The Dawn of the “Bioelectromagnetic Age” is upon
us.
65
Conclusions
Derek Clements-Croome
The Roadmap has distinctive themes which set the pathway for the future.
WHAT ARE INTELLIGENT BUILDINGS?
Intelligence has three parts cognitive, emotional and practical. A building needs to reflect this. So
an intelligent building will responsive to people in terms of not only being functional but to the
human senses besides serving a community in the location. It will be resource effective in terms of
energy , water and waste with low pollution. It will be smart in terms of technology selected to
enable the systems to respond effectively but also make them easier for people to use. Today there
is a focus on health and wellbeing and so intelligent buildings must produce a healing environment.
Buildings need to be functional and practical but also expressive. Equally important is the
infrastructure that services buildings and the people moving between them.
LESSONS FROM HISTORY
Intelligent buildings are not new. Various periods in history just express them in different ways.
Vernacular architecture shows how people from all parts of the world have adapted to working and
living in all sorts of climates. From the igloo in the Arctic to yurts in Mongolia and the Malaysian
house all are examples. The wind towers and mashrabiya in Islamic architecture show how natural
ventilation and shading can be achieved in a natural and aesthetic way. The basic principles of
passive design are embedded here in the vernacular across the ages and is highly relevant today in
order to reduce energy consumption. These basic principles remain true today even for highly smart
buildings endowed with high technology.
LESSONS FROM NATURE
Biomimetic architecture uses Nature as the inspiration because it is economic in use of energy and
materials. Whether it is spiders webs that stimulated Frei Otto to build lightweight tension
structures or the radiolarian which were in Buckminster Fuller’s mind for his designs of geodesic
domes besides many more examples leads us to believe Nature has an abundance of examples
which can inspire architecture. Bernard Rudofsky’s book in 1964 Architecture without Architects
is a reminder of this belief.
Biophilia is our innate love of Nature and it can calm and soothe working or living conditions so
they are less stressful.
Bio- facades using smart bricks embedded with microbes that generate electricity; chemo
luminescence---like the fireflies or angler fish-- for lighting without electricity ; algae living
walls to harvest and derive bio- gas; use of walls with artificial leaves using photosynthesis to
generate hydrogen are just some ideas.
BUILDINGS FOR PEOPLE
Our designs affect people’s physical, mental and social wellbeing. The environment with other
factors is a significant cause of absenteeism and presenteeism which in the UK cost about £100bn
a year So for many reasons including productivity the intelligent building must be a healthy place
to live and work. The latest work by World Green Building Council and their regions; BCO and
others are reviewing the methods for rating health and wellbeing including the WELL Standard,
Fitwel and Flourish models among others which give a holistic assessment of physical, perception
and economic factors.
66
ROLE OF TECHNOLOGY
The rapid pace of technology and the opportunities it offers cannot be ignored. However there are
downsides too . Buildings need to focus on simplicity not complexity. The Fourth Revolution is
underway and robotics; quantum computing; internet of things; smart materials; nanotechnology;
3D/4D printing; artificial intelligence are some of the technologies which are already impacting
architecture. Intelligent buildings need to be adaptable to change to use the opportunities offered
by these technologies for new and old buildings.
SUSTAINABLE ARCHITECTURE
Effective and efficient use of resources like energy ,water and waste is vital so CO2 emissions and
pollution are low. Low or neutral carbon buildings can be improved so we see the emergence of
carbon positive buildings. Buildings can become energy generators.
DECISION MAKING
At every stage in planning, design, construction , commissioning and post occupancy evaluation
decisions have to be made which offer continuity from one stage to the next. There has to be a
vision. There has to be connectivity between all the stakeholders. The latest work on decision
making with respect to ‘wicked’ problems will be reviewed and a transdisciplinary approach with
collective thought advocated using holistic and systems thinking. Success depends on stakeholders
collaborating as an integrated team. Long term thinking is essential with an emphasis on value not
short term costs.
POST OCCUPANCY EVALUATION OF INTELLIGENT BUILDINGS
We need to share successes as well as failures so we do not keep repeating the same mistakes. Let
us be an open forum to learning from each other.
Intelligent Building have existed for thousands of years but different centuries and cultures express
them in different ways so what is an intelligent building? Is it one that serves the needs of people
in functional ways but is also beautiful not just visually but in the simplicity and sensory ways it
achieves these needs. Examples might be an igloo, a Japanese tea house, the Malaysian house or a
courtyard design but there are many other vernacular types throughout history each offering
ingredients that make up the recipe for the essence of an intelligent building.
In the 21st century intelligent buildings tend to be ones that are very technology driven but already
we can see the impact of changes in society in that they need to be responsible for health and well-
being of the occupants so bring in a caring and humane approach that offsets the hard faces of
construction and technology. Too often an intelligent building is reduced down to the choice of a
building management system but there is much more to it than that.
During his lifetime Wotton published two works: The Elements of Architecture (1624), which is a
free translation of de Architectura by Marcus Vitruvius Pollio, executed during his time in Venice
and a Latin prose address to the king on his return from Scotland (1633). Wotton shares authorship
of the quote "Well building hath three conditions: firmness, commodity, and delight," with
Vitruvius, from whose de Architectura Wotton translated the phrase; some have termed his
Elements a paraphrase rather than a true translation, and the quote is often attributed to Vitruvius.
Today that phrase might be durability, resilience, function and beauty.
Of course these are basic primary needs but they can be interpreted in various ways. Each building
will be nuanced in a particular way according to the design team. It is a composition but unlike a
music score composed by one mind buildings are a composite of many thoughts from many minds
67
that make up the design team, many educated in different ways too, and therein lies the source of
many problems. Attaining connectivity of thoughts to achieve a vision is not easy but when
successful is powerful.
Can Intelligent Buildings provide alternative approaches to heating ventilating and air-conditioning
and buildings? Lessons from history as well as the natural world show that they can. These feature
in Chapters 2 and 3. Throughout history clean air, sunlight, sound and water have been fundamental
to the needs of people. Today, sensitive control of these needs may use either traditional or new
solutions, or a blend of these, but we have to remember that the built environment is fundamental
to mankind’s sense of well-being and it is the totality of this idea that we need to understand and
value even in this low carbon economy age. Intelligent buildings respect these values for the
individual, the business organisation and for society, and we can learn a lot about intelligent
buildings by looking at the history of world architecture and seeing how people have adapted
buildings to deal with the rigors of climate and the changing face of civilisation. There are also
lessons from Nature because animals and plants have evolved to use materials and expend energy
optimally in the various changing and dynamic environments across the world in deserts, arctic
regions, hot-humid, hot-dry or temperate climates. Similarly buildings are now having to absorb
the impact of the technological age, but the implications of climate change and the need for healthy
working conditions are now dominating our thinking as people become more knowledgeable about
the impacts of the environment not only on ourselves as individuals but also in the context of
communities locally and globally .
Intelligent buildings should be sustainable, healthy, technologically aware, meet the needs of
occupants and business, and should be flexible and adaptable to deal with change. The life cycle
process of planning, design, construction, commissioning and facilities management including
post-occupancy evaluation are all vitally important when defining an intelligent building. Buildings
comprise many systems devised by many people, yet the relationship between buildings and people
can only work satisfactorily if there is an integrated design, construction and operational team
possessing a holistic vision working together from the commencement of a project. To effect a
common vision, it is essential for architects, engineers and clients to work closely together
throughout the planning, design, construction and operational stages of the buildings total life
cycle. This means that planners, consultants, contractors, manufacturers and clients must share a
common vision and set of intrinsic values, and must also develop a single understanding of how
the culture of an organisation with its patterns of work are best suited to a particular building form
and layout when served by the most appropriate environmental systems. A host of technologies are
emerging that help these processes, but in the end it is how we think about achieving responsive
buildings that matters. Intelligent buildings can cope with social and technological change and
should be adaptable to short-term and long-term human needs, however, from the outset this must
be delivered through a vision and understanding of the basic function of the building.
We need to consider how buildings affect people in various ways. They need to be expressive as
well as being functional. The environments they create can help us work more effectively because
they can present a wide range of stimuli for our senses to react to besides satisfying our primeval
needs of warmth, safety and security. Intelligent buildings are designed to be aesthetic in sensory
terms including being visually appealing; they are buildings in which occupants experience delight,
freshness, a feeling of space, they should invite daylight into their interiors, and should provide a
social ambience which contributes to a general sense of pleasure and improvement in mood. In
Chapter 4 I introduce the idea of flourishing environments. Of course the culture, the management
and job satisfaction are key but this does not subdue the importance of the built environment.
68
Buildings consume a great amount of energy and water in their construction and during their total
life-cycle. They use large quantities of materials and aggregates and generate waste and pollution
at every stage of their production. It is no longer acceptable to consider a building and its systems
in isolation from its social impacts. This becomes critical with the growth of megacities which is
part of a rising trend towards urban living. Modern liveable cities comprise intelligent and
sustainable buildings and infrastructure however they should be designed to show respect for the
natural environment and the health of the inhabitants. Sustainable and intelligent cities are
composed of buildings supported by intelligent infrastructures created for the well-being of
residential, commercial and industrial communities.
The key criteria for achieving good quality intelligent buildings are:
• Satisfying client and supply stakeholder objectives and needs;
• Meeting social and environmental needs
• Recognition of available resources.
An intelligent building starts with a good client brief and should comprise of:
• A clearly articulated project vision and mission;
• A recognition of the planning, design and procurement realities
• Clarity about the use of a whole-life value approach.
By using integrated design teams and user centric design buildings will have effective connectivity
in terms of the occupants and the material resources.. Sustainability and a focus on people adds
value. Lessons for Nature and passive architecture together with the judicious use of innovative
technology can enable flexibility and an economic use of resources.
The creation of shared visions, effective teams, clear structures and robust processes ensures that
the intelligent building being constructed will demonstrate the purpose for which it was conceived.
Times are certainly changing so there needs to be an outlook by the project team which is long
term and not just short-term. In a way this Roadmap is about change as reflected in society besides
the advancements in technology that we create.
